      If I unplug a cable to an active interface (static with DHCP on multiple vlan), some time when plugin back, the interface losse his IP interface causing the DHCP to defect.

      I have to go to the interface panel, and save them again in order to fix this.

        I am not seeing this happen. If you are on the latest snapshot, please post your dhcpd log and the steps needed to reproduce this problem.

          In fact I have this in my system.log :

          Aug 20 17:39:07 pfsense kernel: swap_pager_getswapspace(12): failed
Aug 20 17:39:07 pfsense kernel: swap_pager_getswapspace(16): failed

Aug 20 17:39:07 pfsense kernel: swap_pager_getswapspace(12): failed
Aug 20 17:39:07 pfsense kernel: swap_pager_getswapspace(16): failed

          So lot's of process are dying…

          I'm running a nano build... What can be the cause ?

          It occurs only when I unplug the trunk cable (or applying some settings on the switch which cause up/down).

            It's running out of RAM trying to do something.

            Is this on a current snapshot, or one from a few weeks ago?

              Running the snapshot from Yesterday. I'll try to figure out which process is eating all the memory from time to time.

              Php seems to be the culprit, eating all memory for other process, the system became unstable (and need a hard reboot) :

                Ok I've more informations.

                I can reproduce the issue when I'm applying a new configuration on my switch (wich up/down the trunk link).

                My pfSense box is as flow 2 NICs : 1 WAN / 1 Trunk with 5 VLAN, with 256MiB of RAM (actually 30% used during normal running).

                Here is the ps when the issue occurs, I have a lot of php scripts eating memory and I have also duplicate processes like dhcpleases (12 process with same parameter in the same time, my host file is corrupted).
