[Freeswitch-users] Can FreeSWITCH go into idle mode or something?

I have a completely clean installation of FreeSWITCH on a brand new CentOS 6. Everything works as it should. But testing over a longer period, I see some issues when after 2-3 days without any device registrations or contact to the server in any way, the server doesn't accept registrations. anymore I get timeouts on all devices. A wireshark monitor does see the incoming SIP requests. But nothing happens. A quick restart of the server fixes everything. The FS log only contains: 2012-01-26 10:40:32.184037 [WARNING] switch_scheduler.c:114 Task was executed late by 2 seconds 1 heartbeat (core) Can FS somehow enter an idle period, if no activity has been made, or what could cause this sort of problem?
