Hi Albert,

This looks like the HP-UX client bug that was the subject of a
bug filed against Solaris:

6538387 HP-UX automount NFS client hangs for ZFS filesystems

I investigated this, and found that the client was losing the
lower bits of the attributes of the created file, such that the
SETATTR was being rejected as RFC 1813 requires; you're seeing
it because ZFS supports a higher precision than UFS.  According
to one of our support people, HP confirmed the bug in their code
(sorry, no HP bug ID), and said that HP-UX 11.31 has a fix for
this bug.
