Intermittently unable to login after 2.4 upgrade



  • Hello,

    I'm hoping someone here may have additional suggestions as to things I should try/look for to troubleshoot and resolve this problem:

    Since upgrading my pfSense router to 2.4 (from 2.3.4) I've been intermittently hitting issues with my router including:

    • 502 Bad Gateway and 504 Gateway Timeout errors from the admin portal

    • SSH logins hang indefinitely without ever letting me get to a prompt

    • Random bad behavior from the router – connections failing, services in a wedged state and showing ports in use that should not be, etc

    No configuration changes were made from when the upgrade was made to when this issue started occurring (within 24 hours of the upgrade, IIRC). Thinking this was related to the memory leaks noted in bsnmpd, I have tried disabling all queries to SNMP, disabling SNMP entirely, and even upgrading to the 2.4.1RC hoping to fix that.  And again this morning, I found myself unable to login to the router.  In an effort to gather more information, I've upped my log file sizes significantly and have enabled remote logging to another server on my network as it would be very difficult to get connected to the physical console on this machine.

    Currently installed packages:
    acme
    mtr-nox11
    openvpn-client-export
    pfBlockerNG
    suricata

    Currently active services:
    dhcrelay
    dnsbl
    dpinger
    ipsec
    miniupnpd
    ntpd
    radvd
    sshd
    suricata
    syslogd
    unbound

    Running with an IPSec tunnel enabled for remote access, but this is used only occasionally.  Other VPN services are not currently in use/enabled.

  • @PiBa:

    Maybe give this possible fix a try?: https://forum.pfsense.org/index.php?topic=137103.msg758174#msg758174

    For some reason that thread didn't come up when I last searched this.  I've applied the patch and I'll report back if I don't see the problem again for ~48 hours since it's yet to go that long.



  • Going on three days and hasn't crashed on me since patching (and I noted that there was an official update to pfBlockerNG that included this).  I think we can say it was the cause of the issue.

    Thanks!
