DHCP Service will no longer start
-
OK so i went away for a couple of days, so I am 100% confident that no config changes were made, but DHCP just up and started failing to start.
Any suggestions? If i disable DHCP on vlan 40 (the one it fails on) it then starts failing on vlan 30 etc..

Rebooting the box fixes it temporarily.
However I then enabled another vlan and it failed again with the same error.
Enabling yet another vlan "fixed" it again.All these vlans had the dhcp service running on them before it started failing.
This behaviour has only started since moving to 2.6.0

This continues to fail. Once it fails, i cannot restart DHCP, i need to reboot the box.
Anyone got any ideas?

OK. I believe it's something to do with ntopng. Removing that package appears to have resolved the issue.
