Hi All, I have a Cisco 3825 with 1GB Ram doing some BGP peering (VERY low traffic, not even 5mbit/s sustained throughput). Memory usage is absolutely fine and sitting at less than 50% utilization, and stable.
The Router's CPU is showing an almost linear increases, and the 'TCP Timer' process is currently sitting at over 70% CPU load. Cisco documentation suggests: TCP Timer When the Transmission Control Protocol (TCP) timer process uses a lot of CPU resources, this indicates that there are too many TCP connection endpoints. This can happen in data-link switching (DLSw) environments with many peers, or in other environments where many TCP sessions are simultaneously opened on the router. What does this actually mean? The router does not make any TCP connections (nor does it receive any - except for the odd telnet to VTY). Radius and Syslog is enabled however, but this is sending UDP traffic... What can I look at possibly to determine root cause and fix? -- Regards, Chris Knipe _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
