Clog high load on 2.2.3 and Bump sched buckets on vmware

[inalto]

Hello,

Looking in the performace panel of the vm containning pfsense  2.2.3 i get a constant 3000Mhz line 100%.

Logged in pfsense, with top i see the clog program eating 100% of the cpu.
Also the memory grows and grows when clog is running.

i had to do a killall -9 clog

df -h states that / has 11% capacity so it not a disk issue.
the vm has 2Gb mem so also the memory is not a problem.

looking in the system logs i see that seems that are not updated since many hours and i get plenty of:

pfsense kernel: Bump sched buckets to 256 (was 0)

any clues on how to fix this?
