The second time within two days now my pfsense has shot itself. So far I
worked out this:

filterdns opens an unlimited number of files (approx 10753).
(Only one filterdns process is running!)

Squid 2.7.9 pkg v.4.3.4 starts logging
  httpAccept: FD 51: accept failure: (23) Too many open files in system
without rate limit (bad design).

The log file grows until the disk is full.

My Internet goes offline, which is when I notice the problem.

Recovery is possible by removing the oversized log file and killing
filterdns.

pfSense 2.0.5 running on APU1 board.

Why is this suddenly starting to happen? The only change I've had
recently is that the internal SSD failed and got replaced with a 2.5"
SATA spinning platter.

Thanks muchly,

Volker
