Problem with /usr/local/ispconfig/server/server.sh

[Snowman]

Hi there,
i have multiserver setup, with mysql database server on second node.
Since last upgrade to 3.0.5.1 it seems that ispconfig web interface requests are not being executed by server. When i execute /usr/local/ispconfig/server/server.sh manualy, it will gives me no output. On mysql server it will return "finished". Can someone give me an advice what should i check or so ...

/var/log/ispconfig/cron.log - there are no errors at all.

Thanks,
Martin
