How to resolve ORA-48181/4 errors seen after recent 19C upgrades/patching

Hi there

I have two odd error messages that are randomly showing after either upgrading 11G to 19C databases or patching 19C databases to Apr 21 or Jul 21 patchsets

1- Non critical error ORA-48181 caught while writing to trace metadata file (.trm) with additional info in alert log showing trace file and Linux error

Trace file name: "/u01/app/oracle/diag/rdbms/<database>/<DATABASE>/trace/<DATABASE>_q002_8622.trc"

Error message: Linux-x86_64 Error: 9: Bad file descriptor

Additional information: 1

Writing to trace metadata is disabled for now...

Trace file show ref to kwqmnslv: err 448

2- Non critical error ORA-48184 caught while writing to trace file 

Howdy, Stranger!
