If you log into the server and try to access that directory, do you
You talked about having non-FreeBSD 5.x clients as well, I think, in an
earlier e-mail -- if a FreeBSD 5.x client wedges on a directory on the
server, will another non-FreeBSD client also wedge on touching the
Is it always the same director(y/ies) in which the wedge occurs?
The behavior you describe above sounds like it might be a problem with the
server, or, that the server generates bad or maybe just different
responses that trigger a client bug for particular directories or in
particular circumstances? With the exceptions of things like distributed
advisory locking (rpc.lockd, etc), bugs in one client won't generally
trigger the problem in another client a the same time unless it's a common
property of the directory they touch.
Ruling out debug.mpsafenet and/or if_re checksum issues would both be
useful things to do.
