Symptoms

You may be running a SQL statement, and get an internal error similar to this:

ORA-00600: internal error code, arguments:[733], [268435104], [top uga heap]

The query will be using hash joins. If there is an explain plan in the trace file, this will contain rows with : HASH JOIN

You can make additional checks in the trace file if the stack contains qerhjFetch.
The call stack may look like the following:

ksmarfg kghgex kghfnd kghalo kghgex kghfnd kghalo kghgex kghfnd kghalo kghgex
kghfnd kghalo qerhjAllocHashTable qerhjBuildHashTable qerhjInnerProbeHashTable
kdstf0000101km kdsttgr qertbFetch qergiFetch rwsfcd qerhjFetch rwsfcd
