Hello,

          I have deployed a new machine to run our engine 4.2.8 using engine-backup to do a full backup/restore to a clean Centos install.

We are now having a lot of errors with  ovirt-engine-dwhd

e.g.

java.lang.OutOfMemoryError: Java heap space

java.lang.OutOfMemoryError: GC overhead limit exceeded

org.postgresql.util.PSQLException: An I/O error occured while sending to the backend.

We had a file from 2015 

/etc/ovirt-engine/engine.conf.d/10-setup-java.conf

ENGINE_HEAP_MIN="5845M"
ENGINE_HEAP_MAX="5845M"

I changed it to

ENGINE_HEAP_MIN=2g
ENGINE_HEAP_MAX=4g

and restarted the engine and dwhd

But am still getting errors.

Regards,

                Paul S.
