CPU utilization high with SASI

Running SFOS 19.5.2 MR-2-Build624 on a ESXi 7.03 server.  Things have been running fine for a few months.  I upgraded from UTM.  Suddenly the CPU utilization went from 5% to 99% at about 21:45 GMT  yesterday. I have rebooted several times.  It goes down a bit but then pops right back up.  I host my own email server.

Sasi seem to be taking a lot of the CPU.  I disabled the Anti-spam service but it would not stay stopped.

Sasi log does not have much.

Any ideas?

Thanks,
