Hi,
yes, dnsmasq has some stability issues. This has become way better since a few releases, but it is still not at the level where it should be.
Have you any information about how to reproduce the crash? I experienced them for a time, but they were all random and I could not debug this a lot.
I just merged a patch with some fixes. Maybe it has been fixed in there. Please test Core Update 96 as soon as it becomes available for testing.
Best, -Michael

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:

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