>Description:
Experiencing a kernel panic on one of my production systems. The system is a PF+ALTQ firewall/gateway with
about 1k simultaneous devices behind it at any given time, pushing no more
than 100Mb/s of traffic.
I have completely replaced the hardware to rule out issues with
disk/memory/etc, and it appears to be a kernel issue, likely with e1000/em(4) network interface driver.
The panic seems to happen during times of heavier use, but the frequency is
not very predictable (anywhere from a few times a day to a once a week), so I
feel like its some kind of strange traffic pattern that I am unable to
pinpoint.
I am using a slightly custom kernel based on GENERIC, mainly to bring in ALTQ
and some other options.
Here is the kernel conf...
