High CPU for CTS v1.9.1 Endpoints once migrated to TMS

Hi Everyone,

Since migrating all endpoints over to TMS 14.2.1 from CTSman, we are randomly getting the follwing SNMP traps from the CTS endpoints.

XYZ@ABC.com.au - SEV:1 - Broken - HIGH CPU UTILIZATION - Fri 16 Aug, 2013 - 09:26:23 - High CPU Utilization. The utilization of 86% for CPU instance 768 named CPU: 768 has exceeded the 85% threshold on model XYZ@ABC.com.au.
for more than the acceptable time period. (event [0x00010f03]) - SpectrumRouter

&

XYZ@ABC.com.au - SEV:1 - Broken - No Associated Text - Fri 16 Aug, 2013 - 09:25:52 - High Aggregate CPU Utilization. The average CPU Utilization of 86% for all CPU instances exceeds the 85% threshold on model XYZ@ABC.com.au (event [0x00010f07]) - SpectrumRouter

Does anyone know what CPU 768 means & why this would be happening ? CTS v 1.9.1.

High CPU for CTS v1.9.1 Endpoints once migrated to TMS

Mark.

I have not a direct solution for you, but I heard through TAC about such an issue in the 1.9er version.

Had a very bad behaving TX9000 and one of the questions was, if I manage it with TMS. To my question the answer was that they know about high CPU issues when TMS is involved and 1.9.x

Seems to fit your picture.

Not sure, but with anything higher than 1.9.3 it should be better.
