[Freeswitch-users] Freeswitch stops handling register requests

Mon May 8 12:59:20 UTC 2017

Hello Peter,

thanks for the hint, but can it really happen that events stuck inside freeswitch and freeswitch partially crashed because if this? Or wasn't it more a problem of the 
Client that event’s were discarded if they haven’t been processed fast enough. How many calls did you handle on your server when the problem occurred, are you using inbound or outbound mode of mod_event_socket?

Best regards

Markus

Also the esl socket continued to receive and send events after freeswitch stopped to answer on register events. But maybe it has to do with the esl library like too many open threads or something like that. We recently updated the system from 1.4.26 to 1.6.17, everything was running for 2 days with around 150-200 calls parallel before the problem occurred. I’ve increased debug and monitoring, let’s see if it appears again in the next days.
