JBoss high diskspace consumption during runtime. release upon shutdown

[craneww]

I have a strange situation that I am unable to understand or even explain properly. We run an application that is based upon JBoss 5.1 AS. The application is installed in an LVM mount /opt with 64GB diskspace out of which disk consumption is around 6GB with 58GB free.

Over a period of time (could be days or weeks) the diskspace gradually vanishes. I say vanishes because I can't find any file/folder taking up all the space. When I shutdown JBoss the diskspace gradually appears again. Sometimes it takes about 2 minutes for full recovery.

I am running this application in vSphere 4.1 VM with Redhat 5 x64 OS and there are 15 more VMs on the same host and none of them have such a wierd issue.

I have checked the logs, temp folder etc but I can't find the culprit. Any pointer would be a huge help.

Thanks

Check tmp/vfs folder in your JBOSS_HOME/server/<config> dir.

We had some VFS issues before.

What about if you use JBossAS6?

Thank you Ales. I will check this out next time I run into the diskspace issue. Right now there is no folder tmp/'vfs in the 'default' config directory. Last night when the app crashed I added 40GB to /opt LVM to buy some time and hopefully I can make it to Saturday without any major drama. I will keep an eye out  for vfs folder as you suggested.

The app that I am using is only supported for JBoss 5.1.0. I am using ([The Oracle] 5.1.0.GA (build: SVNTag=JBoss_5_1_0_GA date=200905221053)

Many thanks
