We were also hitting that same error (12547) when we upgraded to version 7.3.4.1 from version 7.3.2.3 . It was not always occurring and only occurred on the server (not on client side using sqlnet). After trial and error when it
did occur, it looks like setting EPC_DISABLED=TRUE fixes the problem. This setting was originally put in a while back (with 7.3) with all our scripts
on the client side. It stops the Oracle Trace logging which causes other problems.

But, then again maybe the bug just hasn't happened lately (last 2 weeks) and we also may need to relink. We are on HP-UX 10.20 .

Was bug 637656 causing this same error EVERYTIME a connect was attempted?

Thanks.
