[QUOTE="mm1352000, post: 796571, member: 82144"] Hi again Jens I can see where the issue is in the logs from January, and I've seen this issue a couple of times with other people since December last year. It seems like TV Server gets locked up because it can't get a new subchannel from TsWriter. TsWriter won't allocate a new subchannel because this can only be done when no other threads are in critical parts of the code. Without getting too technical, this is what we would call a "deadlock". Reproducing such issues can be terribly difficult and finding the cause can be even harder... So how to proceed? I honestly don't know. I have tried before to insert debug to track down this problem, but the sheer amount of data makes the debug output overwhelming and slows down TsWriter enough to affect the actual behaviour of the issue. Are you still able to reproduce the problem at will with the steps you gave in January? mm [/QUOTE]
