On a normal configuration, core.db is written to disk almost every second, generating hundreds of block-writes per second. To avoid this problem, turn /opt/freeswitch/db into an in-memory filesystem, for example by adding:

tmpfs /opt/freeswitch/db tmpfs defaults 0 0

to the end of /etc/fstab , then by issuing

mount /opt/freeswitch/db
/etc/init.d/freeswitch restart

(or the equivalent commands for your OS).
