Description

hey,

about every month i'm getting a panic in pf_purge_expired_states on some
RB_* function.

I talked to dhartmei and he said that there are no problems known to
this code, except for reentrancy issues.

So I wonder: how can the RB-tree be destroyed? Probably some race
between the timer and the network. But can that be? The timer runs in
a critical section, and shouldn't the network too?

several crash dumps available on request.

and clues?

thanks
simon
