With this in place, it seems odd that from one of my queues I

So I have two questions really:
1. Why am I getting different behavior from the two queues?
Could be OS issue - try upping the limit as root from an interactive
shell, and see if you can increase the limit?
Hmmm... If it was an OS issue, I would expect both queues to behave
the same way since both are under the same OS, but they don't.
Curiously, if I try running an interactive job in the same queue
where changing the limits fails in batch mode, it succeeds even
if I am not root. Very strange...
2. Since H_DESCRIPTORS=65536, why can't I request that amount and get it?
I believe you are hitting the OS limit, try something smaller, and/or
change the limit set by /etc/security/limits.conf &
/proc/sys/fs/file-max .

I had already upped the limit in /etc/security/limits.conf:
#
# Up the number of open files allowed - 02 Jun 2011 - JY
#
* soft nofile 65535
* hard nofile 65535
Changing this did not seem to have any effect on the problem.
I'm still baffled why it works under one queue but not under the
other.
