Hello, I am running FS version 1.0.x and trying to move to 1.2/1.4/latest-git. I encounter a few problems which prevents me from using these versions, and would like to know whether someone else is having it. It is quite hard to create debugging information, as with full logging the behaviour is slightly different than lower logging level. The problems appear only on my production system, around noon (when the number of active sessins goes beyond 50-60 sessions): - The voice path is lost in the middle of the session (Jira FS-5616). From TCPdump I see that FS receive the audio from both sides but stops sending it; there is nothing meaningfull in the logs. - FS starts to get sluggish, fs_cli is stuck, SIP messages are processed in delay (5-30 seconds). This goes away by itself after a few minutes. - sessions are left "in use" after the users hangup, and the number of active sessions starts rising. Doing uuid_kill succeeds once (next times fail with "no such uuid", but "show channels" still shows it. The most frustrating side is that I do not know what exact debugging tools to use in order to submit meaningfull data to FS developers. Thanks! __Yehavi:
