8526	Deadlock in backend code when slave backend disconnects	doug@…	cpinkham	"I encountered a deadlock in the master backend occuring sometimes when a slave backend disconnects. Since I am using the feature to make slave backends sleep when they are idle, I was encountering this frequently.

What seems to happen is that code in scheduler.cpp is called from mainserver.cpp while the sockListLock is held. If the scheduler code then calls code in mainserver.cpp, a deadlock can occur.

I have attached a patch which delays calls to the scheduler until after the lock has been freed in the MainServer::connectionClosed() function. 

So far, this is working for me, but I'm not sure if the code currently depends on side effects from the scheduler that are removed by delaying the calls."	defect	closed	minor	0.24	MythTV - General	Master Head	medium	Fixed			0
