opitsk: network error occurred while two-task server trying tosend break
Problem Description: Environment Details
Application Server : Version 10.1.2.3.0 on Windows Server 2003 R2
Database Server: I have installed Oracle DB (11.2.0.1.0) on the same sever having Oracle 11g Release 1 (11.0.7.0) and Oracle 10g Release 2 (10.2.4.0).
I am using Oracle11gR1 listener for all three databases.
I have created database for Oracle11gR2 with no issues at all.
Issue:
Now when I am running my application using Oracle11g R2, my application runs fine for a specific interval after which I get ORA-03113: end-of-file communication channel. All the Sessions linked to these are all dead.
From the logs I discovered this (which is TNS Packet write failure)
opitsk: network error occurred while two-task server trying tosend break; error code = 12571
