This morning I upgraded Asterisk from 126.96.36.199 to 188.8.131.52 along with libpri to version 1.2.3 and Zaptel to 1.2.6. Then stopped and restarted all the Asterisk and Zaptel components. Service resumed as usual but after about 30minutes the console was filled with errors and the PRI ZAP channel (Digium TDM 2 Span) stopped answering calls. The errors where as follows:
pri_dchannel: Ring requested on channel 0/1 already in use on span 1. Hanging up owner
Forcing restart of channel 0/9 on span 2 since channel reported in use
Channel 0/9, span 2 received AOC-E charging 0 units
channel.c:787 channel_find_locked: Avoided initial deadlock for ‘0x74c570’, 10 retries!
At first I thought it might be a problem with my telco provider (BT) but I decided to downgrade to 184.108.40.206 and everything works fine like it did before the upgrade. Im just wondering if something to do with PRI / Zaptel has been broken in the update?. Any Ideas? I really need this update as it appears to fix a bug that I have with IAX2 which stops listening to frames and timeouts all calls even when the latency is averaging 5ms.
