Bug 2489130 - OERI:1112 can occur while dumping PROCESSSTATE informatio (Doc ID 2489130.8)
Bug 4126973: ORA-600[504] AND ORA-600[1112] OCCURED WHEN GETTING "ERRORSTACK"
Base Bug 2489130
Bug 3954753: ORA-600 [1112] AND SESSION CRASH

The cause for the ORA-00600 [1112] appears due to Bug 2489130
This error can occur on dumping of process state which is what occurred here.
The primary issue is the WAITED TOO LONG FOR A ROW CACHE ENQUEUE LOCK!
This then triggers a system state and process state to be dumped due to nature of the problem.
The ORA-00600 [1112] gets dumped out when process state is done.

Stack for trace very similar to Bug 2489130 and this is only known bug on 9.2 like this with a fix.

A fix for bug 2489130 is included in the 9.2.0.7 patchset.
Recommend applying 9.2.0.8 patchset to have this and other bug fixes.
This would only prevent the ORA-00600 [1112] from occurring on state dumps.
The primary row cache issue still to be investigated by performance team.
