Custom form Getting error FRM-40350 Query caused no records to be retrieved

Hi

We are getting error randomly with below error messages

FRM-40350 Query caused no records to be retrieved

FRM-40735 ON_ERROR trigger raised unhandled exception ORA-01001

APP-FND-0154 ORACLE error 3127 audfrm

Cause: audfrm failed dur to ORA-013127 no new operations allowed until the active operation ends

The SQL statement being exceuted at the time of the error was begin fnd_signon.audit-form(:r,:a,:f,:s,:e); end; and was executed from the file &ERRFILE

And after that it is throwing out Oracle Applications, though there are records in table we are getting this error. Need help on finding out root cause of this issue as this is happening randomly.
