Hi all, I'me experiencing trobles with my Asterisk 1.2.4-BRIstuffed-0.3.0-PRE-1 and Patton 4554.
This systme was on a physical machine with ISDn interfaces and since last year we hosted on a VMWARE node.
Replaced the ISDN interfaces with a SIP trunk with Patton, disabled the modules for the zap channels.
Often happens that I had this repeating error on console: Feb 10 11:26:16 WARNING channel.c: Avoided deadlock for '0x9051650', 10 retries!
Then with "show channels" on CLI I found that the channels don't seem to be closed after the calls are ended and so the system fill in with all the calls not ended correctly till the SCCP phones become unreachable, then the SIP, then the voicemail etc etc.
The only solution is to restart asterisk so the channels become empty.
