        Hi,

        I advise you to do what dhcpd is asking you to do :

        /var/db/dhcpd.leases line 0: whitespace too long, buffer overflow.
        

        Delete the file.
        dhcpd will regenerate it.
        Right now, he isn't capable of reading it.

        No "help me" PM's please. Use the forum.

            So its size is zero bytes ?
            That doesn't correspond with the message "whitespace too long, buffer overflow."

            Use console mode, option 8, and the 50 years old command :
            Check if the file exists :

            ls -al /var/dhcpd/var/dbdhcpd.leases
            

            See what's in it :

            cat /var/dhcpd/var/db/dhcpd.leases
            

            Delete it :

            rm /var/dhcpd/var/db/dhcpd.leases
            

            Or use the GUI : Diagnostics => Command Prompt

            Btw
            The file is here /var/dhcpd/var/db/dhcpd.leases and not in /var/dbdhcpd.leases because dhcpd is chrooted into /var/dhcpd.

            Also : what happened that this file became corrupt ? That' quiet very rare. You pulled the plug or something like that ?

              Thank you for that very detailed information.

              Yes it is 0 bytes.

              The problem happened when we had power iinterruption last night. If forces our pfsense box to shut down forcefully.

              After boot up. I added static ip mapping to the dhcp lease.

              After that, i noticed dhcp service doesnt turn on. And this error occurs.

                Using the GUI, right ?
                A human should never use/touch/edit this "dhcpd.leases" file.

                    That likely corrupted the disk, take a backup of your config and do a fresh install. Preferably with a currently supported pfSense version, the 2.3 line is EOL and 2.3.4 isn't even the most current in the 2.3 line. Also get an UPS to protect against power interruptions.
