Hi, Recently it seems that if someone places a caller on hold the system will crash later that evening. Here is what the debug gave me from the output: Nov 25 02:59:53 DEBUG[20526] chan_sip.c: Auto destroying call '76a7a328-999ae7e@10.0.0.3' Nov 25 03:00:00 VERBOSE[20526] logger.c: -- Remote UNIX connection Nov 25 03:00:00 VERBOSE[20526] logger.c: Beginning asterisk restart.... Nov 25 03:00:00 VERBOSE[20526] logger.c: Executing last minute cleanups Nov 25 03:00:00 VERBOSE[20526] logger.c: == Destroying musiconhold processes Nov 25 03:00:00 DEBUG[20526] res_musiconhold.c: killing 20534! However, asterisk never restarted and stopped handeling calls. I was able to asterisk -r and get into it, but no calls could come in or out. I had to actually kill Asterisk and restart it. I am running CVS-HEAD. Has anyone else had this problem? And... how can I disable music on hold to test my theory that this is causing the problem?
