Hello guys,
Finally I have done the upgrade. Theres no more deadlock now ! Thanks. Something still goes wrong and I dont find anything on that : Most of users connected on Asterisk/MGCP cannot place calls because a hang up ringback tone triggered while typing the phone number on the phone. What I can see with Wireshark is : CPE NTFY ; Asterisk OK ; Asterisk CRCX With SDP ; Asterisk RQNT ; CPE OK with SDP ; CPE OK for 4/5 times whereas with a good call this happened 1 time. And in Warning/full : WARNING[11145] chan_mgcp.c: Maximum retries exceeded for transaction 33708 on [030303030303] [Mar 2 19:30:05] NOTICE[11145] chan_mgcp.c: Removing message from 026244104989 transaction 49481 [Mar 2 19:30:07] NOTICE[11145] chan_mgcp.c: Got response back on [026244104989] for transaction 49470 we aren't sending? [Mar 2 19:30:07] NOTICE[11145] chan_mgcp.c: Got response back on [026244104989] for transaction 49471 we aren't sending? I dont understand these outputs. Can you help me to clarify ?

I consider the upgrading to 1.4.29.1. Does it can definitively prevent me from this kind of freeze ?

The process host around 2,4K users. Along the day Ive got some debug reports like : Feb 24 22:25:42 DEBUG[28546] channel.c: Avoiding deadlock for 'MGCP/aaln/1...@028421223635-1' Feb 24 22:29:04 DEBUG[28670] channel.c: Avoiding initial deadlock for 'MGCP/aaln/1...@028421223635-1' Then, at random time (around 10~16 hours after a restart), Asterisk comes into deadlocks : Feb 25 16:28:22 WARNING[8149] channel.c: Avoided deadlock for '0xb713cb60', 9 retries! Feb 25 16:29:07 WARNING[8180] channel.c: Avoided initial deadlock for '0xb713cb60', 9 retries! Feb 25 16:40:21 WARNING[8629] channel.c: Avoided initial deadlock for '0xb713cb60', 9 retries! Avoided seems to correlate that Asterisk is in deadlock status. I put in attached a gdb output during the deadlock if it can helps. How can I correct these errors and avoid the crash not the deadlock J Regards, Adrien .L That kind of "Avoided deadlock..." messages, typical for early 1.2 systems have gone on recent versions on 1.4.X and higher. Did you consider upgrading? Regards, -- Ing. Miguel Molina Grupo de Tecnología Millenium Phone Center
