Description:In a call centre with cca. 1000 calls per day, I am randomly receiving the following warning:

"WARNING[23558] channel.c: Avoided initial deadlock for '0x9fd130', 10 retries!"

It seems like it has to do something with hanging up the ZAP channel, but I am not quite sure as the whole thing is hard to reproduce. In fact the only way to reproduce it is to put the machine under stress test with calls comming in and out every second and watching the log files. The strange thing is that these warnings seem to appear completely randomly. One hour there could be 10 of these messages per hour, and some none - with the same stress.


Asterisk is running on Dell PowerEdge 2500, with the latest RedHat 64 bit OS.

I have attached a log file with most deadlock warning reported so far. Please let me know, if you need any other files (configs or so...).
