I think someone mentioned an exclude list as a possible solution to this
problem.
What about an include list instead (or in addition to the exclude list)?
I'm envisioning something like CellServDB, but without the actual DB info
-- that is effectively a list of robust and/or often-used cells for which
you're willing to look up AFSDB/SRV records?
If neither file exists, revert to the current operation.
Just an idea...
PS. Forgive me if someone mentioned that and I overlooked it. While I read
all the messages in the thread, I'm often interrupted by work...
Cheers,
Stephen

Yes and things are changing over years so that you never know the real
problem. For our cell -afsdb got used since the beginning. But it got
much worse after the debian upgrade to wheeze. At the end all users where
affected. With squeeze it was only noticeable on kde. It may also
correlate with changes on our name server, I do not know about this as it
gets managed central.
Part of the problem is also applications that look for random files all
over the place
I think negative caching and maybe some sort of 'cell-configured' negative
cache file is going to be necessary.
Yes I think this will maybe solve the problem for a lot of programs. But
there are also things like the bash auto-completion which also get
affected by the timeouts where caching maybe wont work that good. But in
this case particular case people learn what they should not use the tab
key in the /afs directory.
In my home network I tested a lot of settings but never got negative
caching with bind working probably. I observe always about 1.3s for
searches which should be cached. At work it was faster.
During the weekend I disabled -afsdb at work on all hosts. I am curios
about the feedback... _______________________________________________
