[jdev] Problem receiving presence after power outage

[Mark Gabriel Paylaga]

Hello,

I've searched in the internet and it seems that jabberd1.4 does not support
the XEP-0198.  Am I correct?
If this is so, do i need to modify my jabberd1.4 files to support this? or
is it better just to send a message to the services in server2 to restart
once server1 has restarted?
