Andy,
Not only can it hang, it can coredump smm and you'll have to
restart Unidata. This happenned to us yesterday on a production server
with 450+ users and 3 other systems connected via nfa, very painfull.
Starts by nfa and new sessions hanging up and then no new connections are
possible.
We are on Unidata 6.1.17 and AIX 5.3. It is supposed to be fixed
in version 7, maybe the core dump scenario is fixed.
Don't know of any way to manipulate this process, its under the
covers.

[U2] [UD] Downed filesystems killing 'udt' sessions
There have been several occasions where on our Solaris machine (which
hosts both Oracle & Unidata 7.1.0 simultanously! -- yeah, don't get me
started there, lol) that some NFS mounts may go offline and become
responsive. This interrupts momentarily our new & active 'udt'
sessions while this mounted filesystem is unresponsive. I guess my
question is, has anybody else encountered this and know of a good
workaround to preventing 'udt' sessions from seeming to freeze until
these filesystems become available? Is there a way to have Unidata
configured to only check pre-determined filesystems & ignore others?
TIA,
Andy
