ORA--07445 error during online Re-org process in 10.2.0.4 database I was doing re-org of fragmented tables in an Oracle 10.2.0.4 production database:

sys@CLARITY&gt; ALTER TABLE SOP_QUEUE ENABLE ROW MOVEMENT;
Table altered

sys@CLARITY&gt; ALTER TABLE SOP_QUEUE SHRINK SPACE CASCADE;
ERROR at line 20:
ORA-03113: end-of-file on communication channel


When I checked the alert log, I found the following error:

ORA-07445: exception encountered: core dump [ktsk_get_prevl2()+217] 
[SIGSEGV] [Address not mapped to object] [0x2E97317530] [] []


What could be the reason for this error, as I am unable to find a proper solution?
Bug 6494048 - Dump [ktsk_get_prevl2] from ALTER INDEX .. SHRINK SPACE (Doc ID 6494048.8)

This issue is fixed in

11.2.0.1 (Base Release)
10.2.0.5 (Server Patch Set)


Upgrade from that ancient, unsupported version.
