[asterisk-users] Avoiding deadlock

[Vilius Adamkavicius]

Hi Moises,

Thanks for your opinion.

However I still wouldn't want to agree that reducing debug logging is a
solution. Let me explain why, we are driving Asterisk using AMI and verbose
logging is simply not enough to investigate issues that arises with our
software or Asterisk itself. Also we are getting valuable information from
the debug logs in order to verify activities in our own logs. Printing
Avoiding deadlock message 12000 times in the logs makes system less
efficient and causes performance degradation due to massive I/O activity.
Would you say this should be ignored too?

I'm not implying that Avoiding deadlock is the problem here, maybe its
Asterisk debug logging?

Regards,
Vilius.
