      Hello,

      I have just checked my logs and noticed a lot of "swap_page_getswapspace():failed (See image below)
      pfsense errorlog.PNG

      How would I go about fixing this?

      Thanks,
      Jord

        What's the output from the swapinfo command and output from the grep command ?

        [2.4.4-RELEASE][admin@pfsense]/root: swapinfo
        Device 1K-blocks Used Avail Capacity
        /dev/label/swap0 16777212 41544 16735668 0%
        [2.4.4-RELEASE][admin@pfsense]/root:

        [2.4.4-RELEASE][admin@pfsenset]/root: grep memory /var/run/dmesg.boot
        real memory = 10737418240 (10240 MB)
        avail memory = 8211410944 (7831 MB)
        [2.4.4-RELEASE][admin@pfsense]/root:

          @NogBadTheBad said in Error in logs:

          grep memory /var/run/dmesg.boot

          When I do swapinfo I receive the following output:
          Device 1K-blocks Used Avail Capacity
          /dev/gptid/2b57240d-1623-11e8-b 1048536 824156 224380 79%

          Doing the second command doesn't give me any output.

            What version of pfSense are you running ?

            It looks like you are running out of swap space, the following should tell you the process that's eating all your swap space.

            Run top -w, press o then type in swap

                grep memory /var/run/dmesg.boot should work.

                How much RAM do you have ?

                  I have just tried running that command again but by tabbing out each word, I don't have a option for memory after typing grep

                  I currently have it set to use 4GB RAM

                    You probally need more RAM.

                      It looks like im using only 48% or am I looking at the wrong thing?

                        The above screenshot is the current state, do you see errors in the log all the time ?

                        https://en.wikipedia.org/wiki/Paging#Unix_and_Unix-like_systems

                        I have 8Gb of RAM and I never swap memory from RAM to disk.

                        Disable ntopng, does the swap usage change ?

                          I see error logs maybe twice a day they have happened since I posted this,

                          When disabling ntopng the swap usage doesn't move but I have noticed that the SWAP usage is 1023 assuming if I upped the RAM this would increase automatically.

                            Upping the RAM causes memory staying in RAM and not being swapped out to swap ( RAM disk ).

                            Can you tie in the time stamps to what squid, ntopng or clamd might be doing ?

                              Just gone through the logs and can't see anything around the time where I received the swap errors
