Solution 2231382.1 : Diameter Signaling Router (DSR): Multiple Call Failures

Applies to:

Oracle Communications Diameter Signaling Router (DSR) - Version DSR 6.0 and later
Information in this document applies to any platform.

Symptoms

Several Call failures

Cause

The issue was caused because a new "dsr" process was initiated accidentally.
The following command ran a new instance of "DSR" process

This command invoked “dsr” process.

203 1485899102:: ps -ef | dsr // When we give a pipe linux executes the command so since there is no grep it actually started the dsr
204 1485899113:: ps -ef | grep dsr

This command lead to starting of one more DSR instance , At the MP blade we need to have only one instance of DSR so when one more was coming up it actually truncates tables and creates issue with already working proper dsr process.
