SEP 12.1.2 filling hard disk with logs and dump after upgrade

Hello,

I recently upgrade to 12.1.2 from 12.1

Upgrade is successful. The next day, cannot connect to SEPM.
Found SEPM service is stopped, and cannot start.

findings

1- SEP Manager cannot start

2- Harddsik is full.

I found that   ...\SEPM\tomcat\bin\ is full of hs_errpid***.mdmp and hs_err_pid***.log.

The .mdmp files cause the HDD full. Need help

Thanks
