Is there any fix for this : CRJAZ1165I Marshalling exception processing request for service

We are noticing that our RTC server is going down very often. The reason was, the DB user is getting locked, due to multiple number of unsuccessful logins. What I presume is, until this exception throws all the RTC users are trying to revoke the session, which eventually gets failed after this exception is thrown. This is what I understood, please correct me if I am wrong here.

I searched for this, I could not find any fix for this. Please let me know how to fix this issue. Thanks!
