ORA-600 [kpotcfnd-3] [36]

(Doc ID 1612751.1)

Last updated on NOVEMBER 28, 2016

Applies to:

Oracle Database - Enterprise Edition - Version and later
Information in this document applies to any platform.


Errors like the following are seen in the ALERT log:

ORA-00600: internal error code, arguments: [kpotcfnd-3], [36], [ORA-00036: maximum number of recursive SQL levels () exceeded
], [], [], [], [], [], [], [], [], []
ORA-00036: maximum number of recursive SQL levels (50) exceeded

The call stack in the trace file may shows functions like:

... kpotcfnd kpcpmap upirtrc upirtr upiver kpusrel OCIServerRelease kpotcgah OCIKCallHandles kwqididqx kpoaqdq opiodr ...


The trace file for the ORA-00600: "internal error code, arguments: [kpotcfnd-3]" does not normally contain the problem SQL.



We expect recursive SQL to be executed, causing this situation.
