[jadmin] jsession.log file? what's in it?

[Oliver Jones]

Hi, the jsession.log file on my Jabber server (1.2) has lots of lines like 
this:

Wed Mar 14 22:01:46 2001  489 5 6 bilajana at jab.dotclick.com/dotclick
Wed Mar 14 22:02:44 2001  105 5 6 frank at jab.dotclick.com/dotclick

Wed Mar 14 22:06:54 2001  910 5 6 superflye at jabber.dotclick.com/dotclick

Can anybody explain what the numbers mean?
Where is this documented?

Thanks!
