    High CPU load, publisher

    Anders Nilsson

      Hi!

       

      Have a question about high cpu load and its behaviour which I don't understand clearly. Don't know how deep I should get, let's start pretty general and see where it takes us. I'm only hosting the server and doesn't work inside Qlikview application.

       

      I get a constant high CPU load on the publisher server, only way I can solve it today is to reboot the server but it always comeback with different timespace.

       

      So when this problem occurs I start to monitor CPU load in process explorer. A big part of the CPU load comes from CPU interrupts.

      I get so bad performence that many realods fails.

      I made some debugging with windows performence records but couldnt make any conclusion at the moment. (May have too look deeper to that).

       

      The server is running in a virtual infrastructure on an kvm hypervisor. The VM has 12 vcpu,(backend CPU is (2x12, 3,4 Ghz,Intel Xeon E5-2600), 48 GB RAM.

       

      Just want to know if anyone has also expirenced this? Dont know if I should start digging deeper to system problems or if it's an Qlikrelated problem.

       

      Thanks!

          In a hardware-only environment, a high cpu load by the 'Interrupts' process is usually an indication of problems with the disks or disk arrays. Not sure if this also applies to Virtual Machines.

           

          I would say that it has "probably" nothing to do with QlikView, but I'm not really sure.
