[OpenSIPS-Users] opensipsctl fifo hangs

[Bogdan-Andrei Iancu]

Hi Brett,

I was checking the CPU load to see if FIFO proc comes to a deadlock (cpu 
-> 99%).

So, further things to check:
    1) error is script (even if parsing related) from the FIFO process
    2) backtrace from the FIFO process after blocking.

Regards,
Bogdan
