I have running this Version since 2 Weeks ... added no new hosts etc.
Yesterday it crashed and zabbix server was not running anymore ...

Here is the logfile output:

3179:20101216:234613.086 Zabbix Server stopped. Zabbix 1.8.4rc2 (revision 15201).

Maybe there is an error. Never had this in other versions before.

Workaround would be to restart the zabbix_server.
