[Asterisk-Users] chan_unical-MFC/R2 CPU usage problem

[Hadi Jadallah]

Hi,

I was running asterisk using the init.d script. Turns out if I don’t use the init.d script and run asterisk either directly 'asterisk -vvvvvvvvvg &' or putting safe_asterisk in rc.local then the cpu utilization problem does not happen anymore.
