Hi, there is a function called pf_get_sport in /usr/src/sys/netpfil/pf/pf_lb.c = which contains a do while loop, the guard is ! PF_AEQ(&init_addr, naddr, af= )). We put a counter in this loop and we saw it spin 431728 times, this app= ears to coincide with a lockup. we'll continue investigating tomorrow.

It might be related to pfsync. Is is the master that panics or the backup? Or both? Regards, Kristof
