High CPU and memory leak after diagcollect

Hi,

I've just upgraded to GRID 19c with RAC including AHF with version 20.1.2 on a Oracle Linux 7.8. All went fine.

There was a little issue after upgrading GRID, hence I opened a SR and made a diagcollection:

"tfactl diagcollect -srdc dbrac"

After doing that I observed later a high CPU load of

"/opt/oracle.ahf/jre/bin/java -server -Xms128m -Xmx256m -Djava.awt.headless=true -Ddisable.checkForUpdate=true -XX:HeapDumpPath=/u01/app/grid/oracle.ahf/data/node1/diag/tfa oracle.rat.tfa.TFAMain /opt/oracle.ahf/tfa"

and the memory leaks down to 1% free.

Restarting of unit oracle-tfa.service kills the process and cleared the memory and lowered the CPU load.

Howdy, Stranger!
