PfSense 2.1-RELEASE (Hyper-V) crash "Panic String: sleeping thread"

  • Hi All,

    We setup 2 pfSense for 2 different offices using the same settings as below:
    version pfSense 2.1-RELEASE (amd64)
    Platform: Hyper-V virtual machine with 4 CPU, 4 GB of RAM, 2 NIC and 40 GB of HDD
    Packages: squid3, squidguard, lightsquid

    Since the systems are in production, one seems crashing every 24 hours only while the other one crashes about every 15 minutes.
    Before being in production (a few days long), not a single crash occurred.
    They both have few load: about 5000 states, 10% MBUF usage, CPU usage 5%, memory usage 15%, etc…

    The Crash report looks like that:
    Crash report begins.  Anonymous machine information:

    Did anyone found a way to solve that issue? I checked on the forum but didn't find any solution :(

    Thanks a lot
