can't send notifications - jenkins disconnects from jabber server

[Luke Sydenham]

Jenkins - 1.6.22
Jabber plugin - 1.3.5
IM plugin - 1.3.5

Every now and then I'm getting a socket closure in the jenkins log and jenkins can no longer publish build events to our chat room on our ejabberd server. Also, I think because the server doesn't see the disconnect it still thinks the jenkins is online and won't allow it to reconnect.

The error log in jenkins looks like...
