An update on this thread.
It looks like Univa has identified the issue and a fix for the error.
I noticed these comments in the Son Of Gridengine v8.0.0c Release Notes:
* Increase default MAX_DYN_EC qmaster param [U]
* Fix qsub -sync y error message and enforce MAX_DYN_EC correctly [U]
I've found some related commits in the github repo.
Anyways, I think a solution might be to increase the MAX_DYN_EC parameter to 1000. I'm going to give that a try in our cluster.

Subject: Re: [gridengine users] error with qsub -sync y
We occasionally get this in our site, and it is pretty catastrophic. Most users have switched to qrsh to avoid the bug. I agree that it happens in batches, for periods of 5-10 minutes. More posts describing the problem are starting to show up on google, since I first ran into it about a year ago.
I tried adding the "-t 1" option to define a range_list, but that did not help.
Most recently, I tried stopping the qmaster and starting it again. That seemed to fix the problem, but that's not a very good solution. We probably wont see the issue again for months. It seems network-load or nfs-load dependent, but I have no data to back up that claim.
Our cluster uses RHEL5.4 and SGE 6.2u5.
