Finally we resolved this issue. It was oracle driver which had some compatibility issue, we upgraded our Oracle client driver to newer version, and this fixed the problem. Base line, there was nothing wrong with application code, code was doing good resource clean up, but oracle driver was leaking handles per every connection.

Resin 3.0.14 I would think "lsof" can give you the information. Otherwise the /proc file system has nodes for introspection of lots of stuff like this. Unfortunately I'm not a black-belt sysadmin, so I don't know the details on how to find it. -Knut Yogesh Gowdra wrote: I don't see any SNMP agents running in our applications, do you see any tools in Linux which I can use and run it against these open socket to get more information, like who and when did they opened? ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Knut Forkalsrud Sent: Tuesday, March 20, 2007 6:28 PM To: General Discussion for the Resin application server Subject: Re: [Resin-interest] java.util.zip.ZipException: Too many open files.

Also, can you make out any thing more from the description of file handles like, are they unclosed POP3 connections or URL connection to external sites? HTTP, POP and SMTP all use TCP, so those are likely not the culprit. SNMP uses UDP, so if you have an SNMP agent going in the app that might be something to look into. -Knut ________________________________ _______________________________________________ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
