CRITICAL
Platform ProcWatch (Device_Name) SW System.RAM_UtilPct, comcol
A process is consuming excessive system resources GN_ABVTHRESH/WRN Metric System.RAM_UtilPct above critical threshold ^^ Current: 95.18 % Onset: 95 Abatement: 95 ^^ [2218:SysMetricData.cxx:665]

Solution

Apply this workaround only if the MP is using DSR function.
The function can be checked from Main Menu --> Configuration --> Server Groups screen.

Procedure:

Disable all diameter connections using Main Menu --> Diameter --> Maintenance --> Connections screen.
Mark the MP as OOS by updating the "Max Allowed HA Role" to OOS from the Main Menu --> Status & Manage --> HA screen.
Execute this command on the MP SSH command line:
/usr/TKLC/dsr/bin/optimizeComcolIdbRamUsage
Bring MP in service.
Enable all the diameter connections.

The workaround shall not be applied if the function used by MP is SBR or PSBR.
