Re: panic in pf_purge_expired_states

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

: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

    Please upload them to your leaf account (or reupload them again since
    the /build partition for non-permanent files had to be wiped).

    I am very interested in wiping out the remaining infrastructure bugs.
