Kernel Panic

[Joe Jones]

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 appears to coincide with a lockup. we'll continue investigating tomorrow.


Regards

Joe Jones

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