Module on Matrix X 16 CPU load 100%

[Tsenislav_Nakov]

Hello guys,
We have a Matrix X 16-slot. On one of the modules we received the following messages:
WARNING: CPU utilization (100.0%) has exceeded the monitored threshold limit (80.0%)
After that all the ports on the module stopped working.
The module is 8 Port XFP GBIC 10 Gigabit Ethernet. After the module was reseated the problem was gone.
These were the processes on the module
Name ProcID 15 Sec 1 min 5 min
domainlink 7 0.26 0.28 0.25
dlm 10 131.80 131.71 132.85
ess 13 41.60 35.60 20.61
fabmIom 14 6.20 6.38 6.18
fem 15 14.13 16.08 17.56

I could not find any information about these processes. Has anyone seen this problem or should i open GTAC case

I would recommend you to open a TAC case for this and if exists please attache the core dump file(s).

[Tsenislav_Nakov]

The version is 2.0.3.0

What version do you use on your X-Series? There exists also a 497 days issue with release 2.0.2.0 or 2.0.2.1 with a known spanningtree issue.

Hello Adam,
Thanks for the quick reply. CA-Spectrum is used. Is it possible that only one module got 100% CPU utilization in this case
