OOM Errors on appfuse.org

All,
Ever since I deployed 1.9.1 to appfuse.org, Tomcat has been spewing OutOfMemory (OOM) errors. It only takes about a minute or two after a restart to get them, which really sucks. I've been doing some profiling this evening and haven't been able to find anything that definitive. However, it seems that Tapestry and JSF are the worst offenders. I can add the other application flavors, and the memory usage gradually goes up as I click through the apps. If I stop clicking, thing stabilize. With JSF, it shoots up and and keeps climbing - almost up 150K. The heap size and stats in JProfiler look good, but Windows Task Manager shows JSF supplying the biggest hit. Does anyone have the time to profile any of the AppFuse flavors? I can send you any information you might need. Thanks, Matt --------------------------------------------------------------------- To unsubscribe, e-mail: [hidden email] For additional commands, e-mail: [hidden email] |

Matt,
I'm unable to reproduce this locally. I'm on XP, Tomcat 5.5.16, MySQL 4.1. Did you have a lot of data in your database? I've been clicking on links/ update/ sort etc for 10 - 15 minutes but the app does not raise an OOM error and the task manager memory footprint also reduces once I stop clicking and settles back to the low value after GC is done. Maybe someone else could try reproducing this. btw what JVM heap size are you running with? And at what memory size are you running out of memory. Do you have a stack trace?
I did notice another thing though while manually stress testing it. Clicking on the the save button of a user reached from "View Users" in rapid succession yields the following exception. I haven't investigated this yet but this probably occurs when multiple threads are trying to update the record concurrently. Not sure if this exception is by design for Hibernate optimistic locking.

I have my JAVA_OPTS set to -Xms256M -Xmx384M. I run out of memory around 550MB +. I don't have a stack trace, but I can get one if you'd like.

Not sure if this exception is by > design for Hibernate optimistic locking. This is b/c we're using versioning on the User object. I left it in their since it seems like a useful feature. In other words, it's expected behavior.

How large is your dataset? I haven't altered the default tomcat Xmx and still didn't get an OOM error. Its going to be difficult for me to troubleshoot without being able to reproduce the issue. Not sure if it will help, but maybe I can also try analysing your JProfiler snapshot at a point when you're see this issue.

I just used a normal database created by AppFuse. The Struts Resume
and wiki datasets are quite a bit larger, but I took them out of the mix. I'll try to come up with a more definitive way to reproduce in the next day or two.

What about setting up a load test scenario with canoo (if this is
possible) or JMeter. Manually clicking around didn't show up OOMs on my system either. Its appfuse latest CVS with jsf (tried struts as well), tomcat 5.5.9, mysql 4.1.15 on XP.

I have a scenario setup with WAPT that I can send. One thing to note
is that these OOM errors only show up when you have all 5 AppFuse flavors installed. Or at least the ones I have on demo.appfuse.org - which includes Spring MVC with iBATIS.

Oh, I see. I've set up a JMeter scenario firing against JSF (the others
not installed) with 10 threads, start,login,4x(userlist,mainmenu)
firing at full speed everything on the same machine with these results: which is very impressive. Unfortunately it's too late over here to do a full-flavour install and setup a test. If I've got time tomorrow, I'll give it a try. M. Matt Raible schrieb: I have a scenario setup with WAPT that I can send.

Here's what I sent to Sanjiv this morning for trying stuff out:I've uploaded all the AppFuse webapps from 1.9.1 to http://static.appfuse.org/webapps.zip. These are just the appfuse applications, which you should be able to reproduce the problem with. Note that they have a JNDI DataSource, so you'll need to create an AppFuse DB named appfusedemo with the specified passwords - or change the META-INF/context.xml for each one. When I originally downloaded everything, I included struts-resume and the wiki. I was able to reproduce OOM without these, so I didn't include them. If you'd like to download the whole ball of wax, I can send you the URL and setup instructions. You should be able to reproduce the problem just by clicking around the applications - particularly JSF and Tapestry. If not, I can send you a WAPT test that'll do the trick.

hmm, cuz I just tried my testing using one AppFuse app deployed (appfuse-jsf). I'll try again with all 5 deployed.
Can you try replicating the OOM with only the appfuse-jsf app deployed?

No, it seems to be the combo. It doesn't go down though, just keeps climbing. I suspect there might be a sweetspot (768M or something), but I doubt it. I suspect a memory leak in one of the combos.

I spent around around 30 mins today having all apps deployed but wasn't able to replicate the issue. Can you sent the stack trace? Is this deployed on a windows box?

Yes, it's a Windows box: AMD dual core 3800 (2 GHz) with 3 GB of RAM.
I'll reproduce and send the files tonight.

Do you have McAfee installed? A recent patch was really buggy and didn't release file handles correctly resulting in a leak of non pooled memory. This could case the error to show up as a OOM.

Nope, but I do have Norton Antivirus installed. Regardless of what I
have locally on my Windows box, the problem still happens on the Linux box where it runs. ;-) Matt On 4/18/06, Sanjiv Jivan <[hidden email]> wrote: > Do you have McAfee installed?

In reply to this post
by Matt Raible-3
Here's what I did to reproduce the problem.
Installed all webapps from appfuse.org in $CATALINA_HOME/webapps. This includes all 5 AppFuse flavors, the wiki and Struts Resume. I started Tomcat (5.5.16 on JDK 5) with JProfiler and all bells and whistles enabled. I completed the following sequence, starting with appfuse, then appfuse-spring, then appfuse-webwork. 1. Login 2. Click on Edit Profile 3. Click Save (there's an error here in Spring+iBATIS) 4. Click on View Users 5. Logout When logging into the WebWork version, I ran out of memory and received the following stack trace: [appfuse-webwork] DEBUG [http-8080-3] UserAction.edit(92) | checking for remember me login... [appfuse-webwork] ERROR [http-8080-3] [jsp].invoke(704) | Servlet.service() for servlet jsp threw exception org.apache.jasper.JasperException: File "/webwork" not found at org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:50) at org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:407) at org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:114) When I tried to access appfuse-tapestry, I received: Apr 18, 2006 9:43:42 PM org.apache.catalina.connector.CoyoteAdapter service SEVERE: An exception or error occurred in the container during the request processing java.lang.OutOfMemoryError: PermGen space JAVA_OPTS: -Xms256M -Xmx384M CATALINA_OPTS: -Xms256M -Xmx256M For kicks, I tried starting Tomcat outside of JProfiler and went through the same sequence of steps outlined above. I actually made it through each application ... almost. I clicked logout on the last one (appfuse-tapestry) and OOM: [appfuse-tapestry] DEBUG [http-8080-Processor25] UserSecurityAdvice.afterReturni ng(118) | Removing 'mraible' from userCache [appfuse-tapestry] ERROR [http-8080-Processor25] [jsp].invoke(253) | Servlet.ser vice() for servlet jsp threw exception java.lang.OutOfMemoryError: PermGen space Matt On 4/18/06, Matt Raible <[hidden email]> wrote: > Yes, it's a Windows box: AMD dual core 3800 (2 GHz) with 3 GB of RAM. > I'll reproduce and send the files tonight. > > Matt > > On 4/18/06, Sanjiv Jivan <[hidden email]> wrote: > > I spent around around 30 mins today having all apps deployed but wasn't able > > to replicate the issue.

ah, did you try increasing the max perm size (-XX:MaxPermSize=256m) . Max Perm size is running out of memory and not necessarily the main memory. Class metadata stuff is placed in the perm memory (google for more deails) and since we're using Spring , Hibernate and Tapestry which all use a lot of reflection, proxying etc, its not surprising that max perm size is running out of memory..

Some javascript/style in this post has been disabled (why?)
Also if memory serves me right, there is a view in JProfiler which specifically shows the max perm memory heap.On 4/19/06, Sanjiv Jivan <[hidden email]> wrote:

Dude - nice work! I added -XX:MaxPermSize=256m to my JAVA_OPTS and
I'm now able to hammer all 5 apps with WAPT and have no memory issues. I've been getting 8 pages per second for 15 minutes with a blip on the error graph every 5 minutes or so. Thanks Sanjiv!
