Hi, what are the possible cause of the critical errors: 2011-12-15 19:14:37.538948 [CRIT] mod_sofia.c:4189 Error Creating Session 2011-12-15 19:14:37.538948 [CRIT] switch_core_session.c:1775 The system cannot create any sessions at this time. 2011-12-15 19:14:37.538948 [CRIT] mod_sofia.c:4189 Error Creating Session 2011-12-15 19:14:37.548945 [CRIT] switch_core_session.c:1775 The system cannot create any sessions at this time. 2011-12-15 19:14:37.548945 [CRIT] mod_sofia.c:4189 Error Creating Session 2011-12-15 19:14:37.548945 [CRIT] switch_core_session.c:1775 The system cannot create any sessions at this time. 2011-12-15 19:14:37.548945 [CRIT] mod_sofia.c:4189 Error Creating Session and so on. This kind of errors appear in a specific time interval (for example from 19:14:31 until 19:14:39) and after this time interval all continue to work normally. This is not a "max_sessions" related problem because in this case appear a "Over Session Limit!" message. I think also that this is not a "min idle" problem because I have not set this parameter, my status is: UP 0 years, 0 days, 15 hours, 26 minutes, 32 seconds, 182 milliseconds, 131 microseconds FreeSWITCH is ready 4279392 session(s) since startup 3463 session(s) 30/100 6000 session(s) max min idle cpu 0.00/77.00 What are the possible causes of this message?
