Sun Grid Engine: occasional job submission errors

[Joey Mingrone]

We are using Freebsd 8.0 / sge-6.2.2.1_1on a computing cluster
(http://awarnach.mathstat.dal.ca/).  It's been working well, however
we see the error below when a lot of jobs are submitted in a short
time (e.g. in a loop on the command line) using
"qsub".

error: commlib error: can't connect to service (Address already in
use) Unable to run job: failed sending gdi request. Exiting.

Has anyone seen this problem before and found a solution?

Cheers,

Joey Mingrone
