It seems that you has got the problem described in Bug4927533, which 
is unfortunately not public and therefore not available on Metalink. 
For more information please read Note:421947.1, Ora-7445 [KGHADJUST] 
Pmon Process Terminated And Instance Crashed. 
Fixed in version: 
- Oracle 11.1 
Workaround: 
- Set "_BLOOM_FILTER_ENABLED" to FALSE. 
No fix exist for Oracle 10.2.0.3.0. 
I recommend that you use the workaround, this will solve your problem.

ALTER SYSTEM SET "_BLOOM_FILTER_ENABLED"= false;
