Hello guys,

customer's CSM randomly reset TCP connections without any log message, or reload csm module.


reason of the reload is: Oct 5 09:16:08: %CSM_SLB-3-UNEXPECTED: Module 7 unexpected error: FPGA4 exception encountered.


sh mod csm tech-support utilization shows:


MACs UNICAST 99% (5572/s)


can anybody explain me what's that means? maybe too many unicast flows on the csm and that is a reason of the reload. I can't find any related infos in the documentation.

  • Cisco Employee,

your csm cored.

do a sho mod csm x tech core to get some core file info.

Then you have to exract the core file and send it to us for analysis.

Better open a TAC SR for guidance on how to extract the core file.

Or simply upgrade to the latest version hoping this was solved already.


the 99% unicast means 99% of the traffic received by the CSM is unicast and 1% mutlicast/broadcast. This is normal.
