Cpush works fine without any problems when ran outside of crontab. I will try running cpush in crontab to see what happens. I did wrap a simple shell script around sync_users and used crontab to launch the shell script. This, too, failed.
I believe that the messages in the log are sent via the logger utility. This doesn't make any sense to me, and I'm not sure why this hasn't worked on two separate clusters.
