I am using Trixbox 2.6.1 which is running Asterisk 1.4.20-1 . Today its service 'asterisk' stopped responding, no once could make/receive calls, if I ran command '
"service asterisk status"
it returned output
"asterisk dead but subsystem locked"
If I restart service asterisk then it resumes calling. Today I restarted asterisk than 10-15 mintes later it hung again so i had to restart it again.
I checked all relevent log files but did not any clue why this service hung. Now i have enabled debug logs to find more granular logs to identify the issue if it appears again.
Is there any other way to find out the root cause why asterisk service behaved like this ?
