[Condor-users] help about too many open files/ulimit by condor_starter

Dear Condor Experts,

Recently, I always encountered too many open files error when submit jobs to condor pool, no matter how many I have set nofile in /etc/security/limits.conf.

I make a script "test.sh" only containing one line to test:
ulimit -n

When I run this script through 
ssh node1 '/tmp/test.sh'
, then it returns 1024000 which I set perviously.

But when I run this script through condor_submit, it always returns 1024.

Anyone has any idea about howto overcome this kind of error?

Or how to config Condor 7.4.2 to return 1024000 not 1024?

All my nodes are ubuntu 9.04 and condor 7.4.2, the linux core is
Linux Brain 2.6.28-19-server #61-Ubuntu SMP Thu May 27 00:22:27 UTC 2010 x86_64 GNU/Linux

Thanks in advance,
