(In reply to napTu from comment #5)

These crashes do not seem igb-specific for me.

It seems, you run something like mpd daemon serving lots of users with NAT and
Netflow processing, do you? If so, have you applied some non-default system
tuning? Specifically, what is your sysctl net.isr.dispatch setting for this
router?

It is generally not recommended to run busy mpd servers with 32 bit FreeBSD
version due to stability problems even if a router has less that 4GB RAM.
Have you read my notes on the topic (in Russian)
