High CPU usage with Wed Nov 5 08:56:01 EST 2008 snap



  • I've got between 30% and 50% or more CPU usage constantly with this snapshot. Top attributes it to "system", so it's hard to tell the cause.

    I thought it might be something to do with snort, but I uninstalled the package and it's still happening.



  • I think this is related to slbd. I just realized I also made a change to the ICMP monitoring IPs for my gateway failover load balancing group. It was having trouble getting responses from the IPs I gave it during that change, and appears to really freak out about it.

    I changed the monitoring IPs to the local IP of my cable modems and now the high CPU usage is gone.

    This also is probably related to my "CARP related crash" thread:
    http://forum.pfsense.org/index.php/topic,12469.0.html

    I've also seen messages about "no buffer space" when trying to ping from the pfSense console after messing with the gateway monitoring IPs. It's like it queues forever in a loop that can kill your box if it can't reach those monitoring IPs. That doesn't seem right…?
