- ALTQ - SW_WATCHDOG - QUOTA - IPSTEALTH (disabled in
loader.conf) - IPFIREWALL_FORWARD (touches every packet, power
users which need a bigger PPS but not this feature can
recompile the kernel, discussed with julian@) - FLOWTABLE
(disabled in loader.conf)
Which is not the same as it's not 100% disabled and will still
allocate memory.
FLOWTABLE on 8.x crashed BGP routers (kern/144917). I don't know if
it is fixed by now, but this kind of potential problematic features
should not be enabled by default.
Agree, I've run into problems with FLOWTABLE (with just the features
that were enabled by default in 8.0) when routers changed MAC
addresses. As far as I understand it, FLOWTABLE is both broken and
abandoned (but if I'm wrong, please let me know).
So, IMHO, not only should it not be enabled by default, but given that
it was disabled complete in 8.x after 8.0 (too lazy to look at exactly
when right now), I think it shouldn't even be included, since that
might encourage users to try it out only to encounter problems with it.

Definitely yes, I'd some problems too with FLOWTABLE running for router.
So I have to disabled in kernel and sysctl.
To make sure I understand you correctly: Did you disabled it with the
sysctl/loader-tunable and everything was OK again, or did you had to
remove it from the kernel config (disabling via sysctl was not enough)
to resolve the issue?
I have one report where a person has issue with FLOWTABLE, but
disabling it via the sysctl/loader-tunable was enough to address his
concerns.
Bye,
Alexander.
