      I also found a few Google references to that Mellanox driver and weird issues with hangs and other problems. That driver may be a problem even though you say it identifies as an "em" driver.

      If the flow manager hang bug patch was truly not present in the current Suricata binary build on pfSense, I would expect to be seeing a flood of messages here as that bug always showed itself after only a few minutes of "up time".

          Are you running on bare metal or within a VM? Curious that Suricata is only opening a single thread for I/O. That indicates your NIC is exposing only a single queue. That would be expected in a virtual machine using an emulated adaptor, but is a bit unusual for bare metal. Most bare metal NICs have at least two queues, and many expose four.

          Also, what rules package are running that is generating the missing MD5 checksum list? That error should not be happening, and the fact it is getting logged means those rules are doing nothing for you.

            yes, it is installed on pc directly
            the nic is a Intel(R) PRO/1000 PT dual port, installed in the vga pcie slot, as it is a bit longer than the standard pcie slot. does this matter?
            the mb is an asus prime, cpu intel celeron G5905, 8GB ram
            i will deactivate all the rules again, so it won't generate that error anymore
            edit:
            hmm i was using et rules, but the errors stays after deactivating them all.
            the builtin rules are the ones generating errors. i mean files.rules, httpevents.rules, etc
            thanks

              That NIC is a plain-vanilla older Intel card. It should not be using the Mellanox driver. Not sure where that boot message is coming from. But that Mellanox driver has been included in pfSense since 2.4.5 or perhaps even earlier.

              I don't believe those errors are related to your hang condition, but they indicate something is not configured 100% correctly. The message indicates you have a rule referencing a list of MD5 checksums, but the file containing that list is not in the referenced location -- hence the logged error and the failure of the rule to load properly.

                    No, I think you are mistaken there. Those built-in rules should not be referencing any md5 checksums. I have ET-Open and all the built-in rules enabled in my test VMs, and I don't get that error message. Have you created any custom rules by chance? Or have you specified a custom URL for downloading rules packages?

                          Have you checked the suricata.log file again after doing this? That file is recreated with each startup of Suricata on an interface. The built-in rules are not causing your error.

                              yes, it is installed on pc directly
                              the nic is a Intel(R) PRO/1000 PT dual port, installed in the vga pcie slot, as it is a bit longer than the standard pcie slot. does this matter?
                              the mb is an asus prime, cpu intel celeron G5905, 8GB ram
                              i will deactivate all the rules again, so it won't generate that error anymore
                              thanks

                              That NIC is a plain-vanilla older Intel card. It should not be using the Mellanox driver. Not sure where that boot message is coming from. But that Mellanox driver has been included in pfSense since 2.4.5 or perhaps even earlier.

                              maybe that mellanox doesnt relate to the nic?
                              did i use the right command to check?

                                  yes, it's the same

                                  You have something unusual going on, then. You can look at the error message in the log and see those rules are coming from a "Black list checksum match" rule. That is not part of any built-in rules.

                                  I suspect you may have some custom rules defined for the interface. And the action keyword for those rules is DROP. No built-in rule is ever shipped with DROP as the action.

                                    Have you checked the suricata.log file again after doing this? That file is recreated with each startup of Suricata on an interface. The built-in rules are not causing your error.

                                    this is what is in the file that gives the error /usr/local/etc/suricata/suricata_16921_em1/rules/suricata.rules
                                    i have in sid management a pcre:. to enable all rules, if it matters

                                      Duh!

                                      Yes it does matter. There is a huge, huge difference in saying "I have disabled all rules except built-in rules" and "I have in SID MGMT a pcre to enable all rules" ... 🙂.

                                      Some of the rules you are enabling are expecting some pre-existing md5 checksum hashes to be present, and those are not there. That's the error. What you do in SID MGMT overrides anything you select or unselect on the CATEGORIES tab.

                                        oh, i see :(
                                        so, then, where do those rules come from if there is no category selected?
                                        and, if they exist, and they do something bad, why nothing appears in the alert, or logs?

                                          ok i unistalled suricata again, and unchecked the keep settings
                                          installed again, and did not enable any ruleset, no sid management
                                          still blocked :(
                                          new suricata log:

                                          if i do the drop all in sid management i get the old log, with the errors
                                          but even without the errors, i still get blocked :(
                                          thanks

                                            I see no block in that log output. What are you saying?

                                            If you mean the interface locked up and is not passing traffic, then I need to see the output of

                                            procstat -t <pid>

                                            like I asked for earlier. I need to see if a Suricata thread is locked or not.
