Great suggestion, Finn! I didn't think of searching on output from truss. First hit looks promising. Per Brandon's suggestion, I've also opened a hardware ticket with our sys admins.

Either that or it's a OS bug. A simple google search on "SIGSEGV SEGV_MAPERR" returns tons of hits on OS issues related to this although most of them are on Solaris. Finn

I've had similar issues in the past where processes were automatically killed for using too much CPU.

I've got a regular job to delete obsolete pieces from our RMAN catalog, which now is failing with "Memory fault".

I even truss'ed the session and it ends with:

...

   Received signal #11, SIGSEGV [default]
     siginfo: SIGSEGV SEGV_MAPERR addr=0x0000000000000058
                                               Err#11 Error 11
occurred.
       *** process killed ***
