I'm no NX expert.
My NXServer (NOMachine) has two running (GNOME) sessions and I can not reconnect to them ?
Even if I stop/start the nxserver daemon, the nxssh sessions are still there.
nxserver --shutdown also fails
Before I do a hard kill, I wanted to know if & how to reconnect them or stop them gracefully.
ADDITION OF LOGS
7:46 is when I failed to connect. 11:57 is when I decide to hard kill

Maybe useful to check log files for errors or anything? If you find anything post them here so we have more information to work with.
Hard killing it wont be a problem but always check logs first.
