Subject: CRS High CPU

Hello group,

I'm troubleshooting an high cpu issue on a CRS-1 running IOS-XR 3.8.2. This is the process responsible for the apparent abnormal cpu
occupation:

    JID   TID PRI STATE  HH:MM:SS      CPU  COMMAND
     1    12  10 Rcv     0:00:04    19.22% procnto-600-smp-instr
     1     7  10 Rcv     0:00:00    10.57% procnto-600-smp-instr
     1     6  10 Run     0:00:00    10.49% procnto-600-smp-instr

This is what i found about this process:

"The microkernel and the process manager together form the procnto process."


Any hints ?


Thanks.
