We have an 18.3.0 DB running on a Centos Linux box (CentOS Linux release 7.7.1908 (Core)) that fails when trying to do a full export on a PDB with
ORA-39014: One or more workers have prematurely exited.

I've searched MOS ORA-600 tool for these parameters with no luck. Any ideas on what can be the issue here or what to try? Thanks in advance for any response.
