Hi,
We have faced a DB crash incident with compressed table. Data corruption in undo and we need to drop/recreate the object to solve
this issue. Have loaded SR for supporting, but the root cause is unknown. Need some advise from this community.

The error of trace is :

ORA-07445:  [_memcpy()+6928] [SIGSEGV] [ADDR:0x
9FFFFFFFBF401000] [PC:0xC00000000029B630] [Invalid Permissions for object] []

========= Dump for incident 103353 (ORA 7445 [_memcpy()+6928]) ========
----- Beginning of Customized Incident Dump(s) -----
Exception [type: SIGSEGV, Invalid Permissions for object] [ADDR:0x9FFFFFFFBF4010


The platform is HP-UX Itaninum 11.31 with Oracle 11gR2 (11.2.0.2.4).

thanks
