Are you contacting the right qmaster, I mean: in principle it's possible to have more than one qmaster (which might overload the exechosts) and as they don't know anything from other instances you can only see the jobs of the actual one. Indication would be, that there is more than one execd on the nodes.

We use ssh global configured:
qlogin_command               /usr/bin/qlogin_wrapper
qlogin_daemon                /usr/sbin/sshd -i
