How to detect and fix healthcheck restarts caused by high memory/CPU usage in Oracle Communications Session Monitor / Palladion 3.x ? (Doc ID 1915553.1)

Last updated on OCTOBER 03, 2018

Applies to:

Oracle Communications Session Monitor - Version 3.3.90 to 3.3.90 [Release 3.0]
Information in this document applies to any platform.

Symptoms

Drops in graphs or service/traffic interruption. Especially if occuring on a probe or ME+probe, temporary packet loss (due to the sniffing services getting restarted).

Here is an example for a very obvious drop in the Active calls graph:

Changes

This issue usually starts to appear because the system is using more memory or CPU than the current configured thresholds - for example after adding new devices, users, concurrent calls etc. Also, even after you fix it by using the solution below, it might reappear after a while so you might need to apply the solution again.
