NFS UDP mounts on RELENG_6?

[Oliver Brandmueller]

Hi,

I'm experiencing problems when trying to mount NFS filesystems from a
RELENG_6 server (FreeBSD hudson 6.0-STABLE FreeBSD 6.0-STABLE
   #0: Wed Dec 14 16:59:55 CET 2005     
   root at hudson:/usr/obj/usr/src/sys/NFS-32-FBSD6  i386)
to either 5.4-STABLE or 6-STABLE clients. mounting works fine, but 
afterwards the access to the filesystem on the client stalls. As soon as 
I mount the FS with a TCP mount everything works as expected.

The mounts worked fine on UDP when the server was 5.4-STABLE. There is 
just a plain GigE switch involved, no firewalls or routing.

Anyone else experiencing those problems or having an idea?

- Oliver
