We have been started to investigate error message by checking below note and also trc files:
Troubleshoot an ORA-600 or ORA-7445 Error Using the Error Lookup Tool [ID 153788.1]
After some searching We noticed that the bug 5868257 is the cause for this issue beacuse of Heap memory corruption and ORA-7445 error has been reported.
This error cause&solution mention in below doc:
Smon Process Terminated Because Of ORA-07445 [Kghsrch()+128] [ID 1189894.1]
For can fix that error We need to apply one-off Patch 5868257.
PS:This fix has been included in 10.2.0.4.1 PSU.In this case applying PSU4 (Patch 9352164) has resolved the issue (PSU4 includes PSU1).The bug are solved in 10.2.0.5 and 11.1.0.6.apply patch of upgrade your db.
