[nsp] pix -to-pix vpn trouble.

[Mehta, Phoram]

I have a fully meshed VPN tunnel network between 4 pix's(506(3), 506E(1)).
Suddenly one of the tunnels between the 506E and one 506 broke. The tunnel
has been re created successfully but no traffic is passing through it. At
one end I see lots of encaps but no decaps and on the other lots of encaps
but very few decaps. The os is 6.1(4). 

Each pix's have 3 tunnels as suggested earlier and besides this tunnel none
of them are having any problems. Interestingly enough, this is the most used
tunnel since it connects the users behind 506E to the Domain
controller(windows 2000 active directory). So they can't print or do
anything on the domain.

Any help is highly appreciated.
