Need help with crash



  • Hi. I recently had my pfsense box crash.  The wiki https://doc.pfsense.org/index.php/Obtaining_Panic_Information_for_Developers says to ask the forums for help with analyzing.  Here's the relevant information:

    Any help would be greatly appreciated!

    There was no clear known cause I could see in the crash report, but everything centered around your bce0 NIC. Hardware issue perhaps? Or maybe some tuning changes need made.

    There were several link state transitions for bce0 along with watchdog timeouts before the crash, but the message buffer isn't timestamped so there is no way to tell if they were immediately before the crash or some time ago:

    I'd be suspicious of that NIC if it were me.
