I will try to setup the environment, but to be honest no more 6.X for us 
until 6.2 or 6.3.. We have lost clients already.

There is one thing I can easily recreate that would very helpfull to solve.
The 6.X NFS clients freeze if the NFS server goes away.

I have been able to reproduce that every single time.. both in test and 
production.

Although solving both, server and client, would be great for us if we could 
at least solve the client.. it would be very helpfull.. until our next 
server comes.. in which we are going to install 5.5

Agree.. but with 4+ crashes in less than a week it has reached the point 
where we have moved workload away from the most problematic machine.. to try 
to aliviate the problem.. but still was not enough.. to prevent at least one 
big customer of ours to go.. We don't keep tight track of the smaller ones.

The problem is when you are a taxi driver... and it cost you money to have 
the car off the streets.. and you don't know when the 'knocking' will 
occur... :-)

Will setup my laptop with the debug settings and will then work on trying to 
debug the client problem... depending on how that goes will then possibly 
try the server that is giving us problems.
