[arg]

Ah this is a ORA-600 error. and I dont have metalink access at the moment. If you have a metalink account, and you should! look for the ORA 600 error message lookup tool.

Solaris? fix:
Increase the unix kernel parameter SEMMNS to a higher value. This will allow
the database to started with a higher processes parameter.

New database?
Perhaps lingering oracle instance with same SID out there?
