Sun Java System Messaging Server - file system full

Hi all,

sometimes my server where is installed Sun Java System Messaging Server 6.2-6.01 (built Apr 3 2006) use all swap space and stop to work.

This is strange, the only log useful I find is this (into messages):

Mar 29 13:40:45 srvmsg01 tmpfs: [ID 518458 kern.warning] WARNING: /tmp: File system full, swap space limit exceeded

There are no warning or error into imap, pop, http, maillog.

My normal file system is:

Filesystemkbytesusedavail capacity Mounted on

/dev/vx/dsk/bootdg/rootvol

Do you know if there are any bug that could make all swap space occupation?

Thank you very much

Best Regards

Marco

So, what's in /tmp when it's full?What's running on your system, other than Messaging Server?What process is so large?Use your OS tools to help you identify what piece of this puzzle is the offending piece. Then, maybe, we can help you out.

Hi,

Following on from what Jay said, the /tmp filesystem can become 'full' either because files in /tmp are consuming all the space or the available space becomes small due to processes consuming virtual memory.

I had a customer case where they ran out of virtual memory due to a badly configured third party virus scanning processes that would consume all available swap.

If the problem happens a lot, perhaps run a looping script that keeps a listing say every 5 minutes of the contents of /tmp (ls -la /tmp), a process output (ps -ef) and vmstat information (vmstat 5 2). That way you can determine what process/files are using the /tmp and work backwards from there.

Shane.

thank you Shane, thank you Jay,

we made just a script like that you describe.

We found that is a "omnivision" process that start large use of memory.

No problem with Sun One Messaging, it works fine!

Thanks again

With kind regards,
