I was/am having the same issue. Updating world (6.2-stable) to include
the above update sadly did not fix the problem for me. This is an amd64
box with only one client connecting to it via nfs. Reading further it
may seem to be an issue with rpc.statd and/or rpc.lockd. As I only have
one client connecting and it is being used as mail storage (i.e. the
client pops/imaps the storage) would be safe to not using fcntl forwards
over the wire? Is this same issue present in 6.1-RELENG? I am really at
my wits end at this point and for the first time am actually considering
moving to another OS (solaris more than likely) as I cannot have these
types of issues interrupting services every couple days.

What other information (spefically) can I provide to help the devs
figure out what is going on? What can I do in the meantime to have some
semblence of stability? I assume downgrading to 5.5-RELENG is out of the
question but perhaps disabling SMP?
