      Hi everyone,

      Since the upgrade 2.7.0 - 20221223, pfsense crashes several times a day. It reboots.
      I get these panic message :
      "panic: buffer modified while frozen!"
      "panic: Memory modified after free 0xfffffe011ec36000(131072) val=dfadc0de @ 0xfffffe011ec40be8"

      I didn't find anything based on these messages.

      Has anyone already encoutered this issue ?

      Best regards,

      Brouls

        You'll need to download and attach one of the crash dump files (e.g. textdump.tar.0, rename it to textdump.tar) or at least extract the text files from it and post their contents. The firewall should be offering to let you do this from the dashboard when you log back in after a crash.

        The two most important parts are ddb.txt and msgbuf.txt which will have a lot more detail about the crash and why it happened.
