7.1-STABLE crash

[Asmodean Dark]

>> Do you really need a such outdated version of mpd while mpd5 is available in ports?
Yes, we need mpd3 because there are many our custom patches for it (some RADIUS functions, bugfixes etc).

>> Do you have some automatic blocker or some other script that periodically add/remove IPs in a ipfw table?
Yes. For some our users we use ipfw-based rules (SMTP port blocking, enabling transparent proxy and other). Mpd ifaceup script contain something like this:
	if [ "$FilterId" = "no_transparent" ]; then
		$IPFW table 3 add $IP
	fi

And, in ipfw.rules:
	add allow tcp from table(3) to any dst-port 80 in recv ng*

Why table can be corrupted? ipfw check added address, isn`t it?

>> Do the bt output for other crashes looks the same?
It`s a first dump obtained. There is some problems in receiving it, because all servers is network-booted (via PXE) and have no usable dump devices :) This dump obtained with USB flash device connected to server. Also, crashes is not often.

Thank you
