      Hello,

      Everything was working fine for the past 6 months until this morning, Pfsense was very slow / not working ( packet loss ect … ) so I rebooted it, after it comes back online I checked the syslog and saw those errors:

      
      Last 100 system log entries
      Mar 23 10:23:30	dhcpd: send_packet: Operation not permitted
      Mar 23 10:23:26	dhcpd: send_packet: Operation not permitted
      Mar 23 10:23:22	dhcpd: icmp_echorequest 192.168.0.196: Operation not permitted
      ...
      Mar 23 10:12:02	siproxd[8688]: sock.c:445 ERROR:sendto() [192.168.0.178:5060 size=775] call failed: Operation not permitted
      Mar 23 10:12:01	siproxd[8688]: sock.c:445 ERROR:sendto() [192.168.0.178:5060 size=775] call failed: Operation not permitted
      
      

      Do you have any idea why it's happening?

      Thank you,

        Thinking out loud here.

        Sounds like the firewall, or something is blocking those packets. Did anyone change anything just recently? If not have a look in your rules maybe something is corrupted. I would restore your config from you last backup.
        Other than that that maybe Maybe a disk or flash corrupting or faulty NIC, but issues?

          @Th4xll:

          Maybe resource exhaustion, no free mbufs. What is displayed by pfSense shell command

          netstat -m

          You might have to type this on the console.

              No requests were denied nor are any of the pools close to the maximum value so it looks as if the problem wasn't one of running out of a kernel network resource.
