[Freeswitch-users] Apparent performance bottleneck and FS freeze

Mon Jul 22 23:59:28 MSD 2013

Its a large number of handles to have open all in sofia if you are not

db_cache status

from cli can show where those handles come from and what db they are using.
Clearly the box is being overloaded past its limits.

This is why we don't endorse virtual servers.
