      Hi,

      It's the second time now that pfSense crashes when I try to reconnect my pppoe session. I disconnect it because it doesn't work, then I try to connect it again. pfSense becomes unresponsive and eventually I get the crash report on the web page.

      See here : https://gitlab.com/-/snippets/2061737/raw/master/snippetfile1.txt

      I have the textdump.tar.0 and info.0 available too.

        The important part of that is:

        So I would certainly try disabling bandwidthd and retesting.

        Looking at the message buffer there is:

        <6>pid 27318 (ntopng), jid 0, uid 0: exited on signal 11 (core dumped)
        

        I would try disabling ntopng too though it quite common to see it fail to start at boot but run fine afterwards.
        There are also a load of logs like:

        pf_test: kif == NULL, if_xname pppoe0
        pf_test: kif == NULL, if_xname pppoe0
        pf_test: kif == NULL, if_xname 
        pf_test: kif == NULL, if_xname 
        pf_test: kif == NULL, if_xname 
        pf_test: kif == NULL, if_xname
        

        That could be miniupnpd or maybe Avahi since it looks like you're not running pimd.
