I am running 95 and have had two times in the past couple of weeks where dnsmasq has died on me. I have been able to fix the problem by starting it up again and it works just fine.
The error appears to be associated with these log entries:
Nov 24 13:38:26 dd-router kernel: dnsmasq[2789]: segfault at 0 ip 0805daaf sp 5af771e0 error 4 in dnsmasq[8048000+32000] Nov 24 13:38:26 dd-router kernel: grsec: Segmentation fault occurred at (nil) in /usr/sbin/dnsmasq[dnsmasq:2789] uid/euid:99/99 gid/egid:40/40, parent /sbin/init[init:1] uid/euid:0/0 gid/egid:0/0 Nov 24 13:38:26 dd-router kernel: grsec: bruteforce prevention initiated due to crash of /usr/sbin/dnsmasq against uid 99, banning suid/sgid execs for 15 minutes.

this is a fresh install of IPFire 94, then upgrade to 95. Please let me know what I can do to further troubleshoot this.
