We've had this issue occur at NCSU as well.  I'm trying to figure out if
1.6.2 will be out soon enough to wait for it, or have multiple outages
for installing the ulimits and then upgrading to 1.6.2 when its
available.  (Or spend weeks moving volumes.)  There are another fix or
two in 1.6.2 I'd like to apply to our servers.
