New submission from Thomas Nikolajsen <thomas.nikolajsen at mail.dk>:

Using 2.2.0-RELEASE w/ HAMMER patch from issue1276 or HEAD
I experience stalls on NFS client, during e.g. buildworld,
it just sits there doing no work; doing some operation on other NFS mount
(same server) kicks client to continue buildworld.

NFS server uses HAMMER for export, no PFS.

NFS client uses NFS mount for /usr/src & /usr/obj &
some other dirs, e.g. home dirs.

Stalls are not very frequent, typically once during a buildworld.

Problem seen rather infrequent on HEAD for a few months.

How is this best debugged?
