Hi, I'm constantly getting following error after around 1 week running freeswitch on quite a low amount of traffic and freeswitch stops to replying to any traffic: 7fcf13e5-4529-464c-87af-67dca8a2eca8 2017-08-09 06:06:06.454889 [NOTICE] switch_channel.c:1104 New Channel sofia/internal/xxxx@myip [7fcf13e5-4529-464c-87af-67dca8a2eca8] 2017-08-09 06:06:06.454889 [CRIT] switch_core_session.c:1799 Thread Failure! 83f02a66-630e-4f59-8716-12a107478059 2017-08-09 06:06:29.494827 [NOTICE] switch_channel.c:1104 New Channel sofia/internal/xxxx@myip [83f02a66-630e-4f59-8716-12a107478059] 2017-08-09 06:06:29.494827 [CRIT] switch_core_session.c:1799 Thread Failure! 2017-08-09 06:06:29.494827 [CRIT] switch_core_session.c:1755 LUKE: I'm hit, but not bad. 2017-08-09 06:06:29.494827 [CRIT] switch_core_session.c:1756 LUKE'S VOICE: Artoo, see what you can do with it. Hang on back there.... Green laserfire moves past the beeping little robot as his head turns. After a few beeps and a twist of his mechanical arm, Artoo reduces the max sessions to 101 thus, saving the switch from certain doom. fs_cli stops to work and freeswitch replies with: SIP/2.0 503 Maximum Calls In Progress Cpu usage is 0. Any hints? Jurijs
