[Freeswitch-users] CPU Spikes every 20 minutes

Thread 7 is the sql thread.
again it points to the sql.

If you are only concerned by the load average and are not
actually experiencing any noticeable problems you should not be concerned.
If you have an actual problem, try a newer OS.  Sangoma cards have been
known to consume more resources on older CentOS due to incompatibility with
modern processors.
