Portal Page goes down randomly

[Rhicinus]

Hello, (pfSense 2.2.6-release)

we use 6 different Captive Portals on one pfSense.
A few times a day especially one of them goes down, i.e. Port 8005 not reachable anymore.
But this could happen to one of the others, too. In Status - services the Captive Portal Service
is marked green, but a restart service brings it up again (until the next time…)

System log shows nothing interesting on lighthttpd (any tips to make it more verbose?) but
some SSL errors (ca 10/minute).

Any hints for me?
