Synopsis: coredumping big programs freeze NFS during dump

State-Changed-Why:
Is dumping core to a local disk better? (As in, other things will run
while it's going on -- nothing will make dumping 2.5G particularly fast)
Also, how is/was your nfs mount set up? Are you using a hard or soft
mount? intr or nointr? tcp or udp? And how good is your pipe to the
filer?
And also, how does the speed and concurrency of dumping 2.5G of core to
nfs compare with dumping 2.5G of /dev/zero with dd?

It does not sound to me like the problem is the core dump per se.
