RE: Core dumps

Jesse, Rich


Just curious: Does the output of "ulimit -a" show acceptable limits as described in the installation guide?  I've recently been shown the light that I've been mistakenly skipping over that requirement, which has at least changed between 9iR2 and 10gR2 for Linux (e.g. "ulimit -p").

Subject: Core dumps

Hello all

Anyone else experience unusually often occurring coredumps and segfaults on (linux) ?

Even the upgrade from to core dumped on me on first run. After flashing the database back and retrying it ran fine. However, now the main application running on this (test) system caused oracle to dump core more frequently then not.

Getting loads of different variants of ORA-7445 :
core dump [qesmmIUnRegisterWorkArea()+628] [SIGILL] [Illegal operand][0x8EA33E0] [] []
core dump [kglhpd_internal()+1298] [SIGSEGV] [Address not mapped to object][0x14C63C8] [] []
core dump [kcbget()+1662] [SIGSEGV] [Address not mapped to object] [0xE] [] []
core dump [eomg_migrate_contents_as_needed()+762] [SIGSEGV] [Address not mapped to object] [0xFFF8] [] []
core dump [ksarcv()+328] [SIGSEGV] [Address not mapped to object] [0x0] [] []
core dump [kcbgcur()+2685] [SIGSEGV] [Address not mapped to object] [0xE] [] []

Anyone experience similar problems with this release ?
