High Memory

We have this odd issue where the CPU is spiking to 88% on avg its 82% and causing the firewall

We have rebooted the firewall which solves the issue for about 2 weeks.

To make it worse cmdbsvr crashed and the firewalls failover.

Tried killing wad but 1 second later its all back.

Plus all demons go into sleep.

FGT is on version 6.2.2.
