Hi,

DB version : 11.2.0.3

host : RHEL
one of our jobs fail with end of communication channel error.

It tries to pull data from another oracle database through dblink. When we check the alert log of the source db, we find the below error..

Exception [type: SIGSEGV, Address not mapped to object] [ADDR:0x0] [PC:0x93665FA, ttcfour()+502] [flags: 0x0, count: 1]

Use ADRCI or Support Workbench to package the incident.

Howdy, Stranger!
