Hi everyone, Has anyone seen anything like this before? Searching on Google etc has revealed nothing.
For a few months now, MX240s running 16.2R2.8 have showed one of the RE CPUs running at around 90%. It has not affected the MX80s in the same network running the same OS and having essentially the same config (simple dual stack network, IS-IS/BGP, that's about it). And none of the 240s started doing this at exactly the same time. And there are no configuration changes around the times the CPU jumped. Here is an example: philip@TCR> show system processes extensive last pid: 33210; load averages: 1.23, 1.15, 1.14 up 343+02:08:01 06:42:04 144 processes: 5 running, 138 sleeping, 1 waiting Mem: 284M Active, 1474M Inact, 183M Wired, 12M Cache, 91M Buf, 32M Free Swap: 4096M Total, 319M Used, 3777M Free, 7% Inuse PID USERNAME THR PRI NICE SIZE RES STATE TIME WCPU COMMAND 11473 root 1 52 0 724M 6048K piperd 3408.8 79.05% python 10 root 1 155 ki31 0K 12K RUN 2883.3 2.20% idle 11367 root 2 -26 r26 813M 8904K nanslp 182.5H 1.66% chassisd 11825 root 3 20 0 903M 39936K kqread 36.9H 0.49% rpd 11387 root 1 20 0 784M 29580K select 119.3H 0.39% mib2d 11863 root 1 20 0 738M 10084K select 76.4H 0.29% snmpd Almost 80% caused by python. I'm not doing any automation (that I've knowingly set up). Jumping into a shell, I see this: philip@TCR> start shell % ps ax | grep python 11473 - R 204530:44.49 /usr/bin/python /usr/libexec/icmd/icmd.py 33362 0 S+ 0:00.00 grep python ICMD according to the docs is the "internal communication health monitor daemon". Weirdly, I only see the ICMD running on the MX240s, not the MX80s. Even though the docs suggest it applies to all MX. https://www.juniper.net/documentation/en_US/junos/information-products/topic-collections/release-notes/16.2/topic-113675.html Any clues at all? Is this just a reboot to make it go away? (Although one has been rebooted recently, and after about two weeks of uptime, the CPU jumped up to 85% and has stayed there.) Thanks! philip -- _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
