I seem to recall a patch for this, but I can’t find it now.   It’s finally 
happened firmly enough that I can reproduce it, on amcheck at least:

amcheck  (and sometimes amdump) hang indefinitely is the client is powered down.

amanda v3.3.6  server    (happened on 3.3.3 too so I upgraded, but it still 
happens)
2 clients - are powered down so version cannot matter!
both are (were) using  auth=krb5  
other krb5 clients work fine  and have done so for more than a year

The server’s log doesn’t have anything useful —  I killed the process at about 
15:10 .

Can somebody point me to the patch I remember hearing about?
