IM Gatway does not release file handles on MSN images

This morning we had an issue with openfire where users were not able to login. after inspecting the logs and some talented work by our technical team it was discovered that the cause was too many open file handles. The relevant log entry was:

2007.12.18 08:23:05 org.jivesoftware.openfire.ldap.LdapGroupProvider.getGroup(LdapGroupProvider.java :107)

javax.naming.CommunicationException: tos-dc4.thinkorswim.com:389 Root exception is java.net.SocketException: Too many open files

The ulimit for the server(jabber) was 1024

Pid of jabber was 11985:

root@chat:/opt/openfire/openfire/logs# ls -l /proc/11985/fd | wc -l 1025

Oops.

An ls -l /proc/28732/fd showed hundreds of:

lr-x------ 1 jabber jabber 64 2007-12-18 08:25 994 -> /tmp/MSN66084.dat

lr-x------ 1 jabber jabber 64 2007-12-18 08:25 995 -> /tmp/MSN66083.dat

lr-x------ 1 jabber jabber 64 2007-12-18 08:25 999 -> /tmp/MSN66093.dat

root@chat:/tmp# file MSN8874.dat

MSN8874.dat: PNG image data, 96 x 96, 8-bit/color RGBA, non-interlaced

We have now increased the ulimit to 64k but this is a stop-gap unless we know that the Plugin (or the server) will eventually release the file handles.

I look forward to the response.

Please see the post I made last week about this:

Thank you that did it.
