Hello,

my netbsd router periodically crashes with a page fault trap in 
netbsd:fr_checkicmp6matchingstate

trace:
fr_checkicmp6matchingstate(cbadaa48,0,28,cbadaa48,8)
fr_stlookup(cbadaa48,c291fff8,cbadaa10,0,cbadaa48)
fr_checkstate(cbadaa48,cbadaa44,cbadaa48,1,6)
fr_check(...)
fr_check_wrapper6(...)
pfil_run_hooks(...)
ip6_output(...)
icmp6_reflect(...)
icmp6_error(...)
ip6_forward(...)
ip6_input(...)

My System: NetBSD 3.1.0_PATCH

I cannot reproduce the trap, I can only wait until it occurs. Sometimes 
after a day, sometimes after weeks.

Do there exists any patches against that problem?

Thank you for your efforts
Uwe
