      I've disabled WireGuard for now and activated OpenVPN. So far so good, no issues since 24 hours.....

        Same issue here on SG-5100s - two wireguard peers (three pfsense endpoints total), similar backtraces. Interface created for the wireguard shared subnet, and MSS clamped to 1420 on the WG interface (it was not clamping in the reverse direction when looking at SYN packet traces otherwise.)

        Allowed IP of each peer set only to the remote CIDR. Peer WireGuard address set to the peer's IP in the WG subnet (which is set as a common /24 among all 3 endpoints.) Distinct PSKs per peer pair.

          @bobwondernut I've had similar issues with 21.02 on two 5100s. Latest incident and write up can be found here

            My problems are gone now with the change to OpenVPN. Disabled WireGuard and all problems are gone for now. No crashes anymore....
