Version: 0.70.90 (using 4.3.1 (KDE 4.3.1), Debian packages) Compiler: cc OS: Linux (i686) release 2.6.31-1.slh.7-sidux-686 after some time all Jabber accouts shows offline (without any notification)
You have probably lost connection and Jabber didn't reconnected, this should be fixed in KDE 4.3.4 and later
I was wrong this is fixed in KDE 4.4
