We've been seeing this issue too. It seemed to be correlated with the
leap second that got added on the 7th. RHEL6 has a bug that causes
issues for threaded applications. We're working on restarting all our
sge_execd's, but not all of them want to softstop properly.
See this knowledgebase article for more info:
https://access.redhat.com/knowledge/articles/15145
We're not totally certain this is the issue, but it's highly correlated
in time with the leap second.

I am intermittently seeing the following on the command line when

error: error running IJS server: "can't create tty_to_commlib thread:

In addition, I have started to see the following in the
spool/qmaster/messages file (unrelated?):
07/11/2012 13:06:02|listen|serverA|E|commlib error: got read error
(closing "hostA/qstat/29971")
These appear to be 2 separate problems as one is qrsh and the other
appears to be qstat.
I am running sge6.2u5
qmaster is running on rhel5
clients are rhel5 and rhel6
The qrsh issue seems to happen much more frequently on the rhel6 system.
Thanks for any help in how to trouble shoot this.
