High CPU usage



  • I have a Dell 2950 with 2 X Xeon 2.0 Ghz procs 4GB of RAM 3 X Intel nics with the 2 inbuild ones all in use. I have Squid and Squid Guard is installed and the CPU perminatly flat lines at 25% - 50% CPU usage with no traffic. Does anyone have any ideas why.



  • try "top" and see if you notice anything that´s hogging up cpu there

    /F



  • $ top

  • So, that must be slbd not squidGuard or squid. SLBD is the load balancer.



  • Is this a known problem with dual core and dual proc machines?



  • If I remember correctly from previously issue, SLBD can randomly run wild. After a reboot it could run normal for weeks.
    As 1.2.1 is to be released i would recommend a upgrade.
