Randomly crashes every few mins



  • All,
    i've been using PFsense for couple of yrs now. Recently it's been crashing more often. it used to crash once in every 30days or so since i upgraded to 2.0.1 But today it crashed every 10mins since morning. I can't get my head around with it. please help. here is the crash report

    Not enough info in just that part of the report (need to see the full/complete one) - but just a guess, as it's mentioning mbufs, you may be running short of mbufs and need to tune some things:

    http://doc.pfsense.org/index.php/Tuning_and_Troubleshooting_Network_Cards

    In particular, look at the nmbclusters change suggested on that page.



  • sorry, cant see crash report now. i will upload the entire report when see it next time. Mean while, I've been using an old PC with one on-board NIC and a realtek NIC. do you think upgrading WAN NIC card to 1gbps intel card will resolve the issue??


  • Netgate Administrator

    What hardware are you using currently? The more details you give us the more likely we are spot any clues.

    However my first thought would be: hardware and software is unchanged but crashes are becoming more frequent, points to some failing hardware. Possibly bad RAM or PSU?

  • alright, that was stable for almost 33 days and crashed again today. It is intel celeron processor with 2GB RAM (upraded from 1GB).
    thanks



  • @jai23155:

    Crash report?
    Power dip?

    This crash isn't necessarily related to previous crashes you reported. Any additional information you can provide MIGHT give a clue leading to discovery of the cause of the crash.



  • Looking at crash reports from the IP you're posting from, you're running a developer kernel. That will panic at times when it doesn't really need to, which appears to be what's happening there. Run the standard SMP kernel and I suspect you'll be fine, doesn't look to be a hardware problem from the crash reports.

  • Thanks cmb, i guess i need to switch to uni-processor kernel.


  • Rebel Alliance Developer Netgate

    We no longer include a uniprocessor kernel. You'll want to use the SMP kernel.



  • Cmb, sorry for the late reply but that did the trick. how do i mark it as answer?
