PFsense Crashed! Please help me identify the culprit

  • This is the crash log. Im using 2.1.5-RELEASE (i386) by the way. I installed a ddr1 512mb pc2700 ram together with the existing ddr1 512mb pc3200. I dunno what happen, it was working fine this morning but tonight it already crashed twice.


  • anyone please help me.. im a total noob on pfsense.

  • Any time I've ever had an issue with PFsense it's been hardware related.  For me it was a bad hard drive, but considering you're running 10 year old hardware (P4-2.66GHz) it could be any one of multiple things.  I would test your HDD and Ram for starters.

    I've never seen this log before, but there are some failures noted that may or may not be related to your crash:

  • I think you may have a point, ive also experienced slow bandwidth output from rl1 interface. Could that be related to old hardware? Im thinking about changing my server(hardware), but i just want to make sure that its hardware's fault.

  • Update: Its been running for 4 hours and not yet crashed. I'm not sure if its hardware issue.

  • I think you may have the same problem I have. I think it's because apinger can't resolve an address. This fills up the log and consequently this fills up your memory and causes a crash,but I'm not one hundred percent sure on that.

  • Im also thinking that its because apinger has failed, for some reason my cable modem keeps on dropping.
