This sounds like the usual 'my server tmp dir is /tmp and I have a cron job that cleans files from /tmp that ar older than 7 days' problem.
dont believe I have any background processes (cron jobs) running besides the app server and the database server.
the Jboss server is installed as a Windows Service using a wrapper from Tanukisoftware.com
WOuld this have anything to do with the problem?
Yeah, silly me. I only saw that you are not on Unix after submitting.
I don't have any experience with the tanuki wrapper so far. Only with another one (JavaService from mulitplan/Alexandria) and that one is ok.
Do you see anything in the logs?
We have servers running (on Linux) jboss with apps and uptimes for more than a month (and then some silly guy just rebooted the whole box).
Could you please tell me how to clean files from /tmp under Linux?
