[j-nsp] commit sync hanging, now config has exclusive lock

I was actually just about to post this....

Yes, we killed the user with a 'request system logout user admin'
(even though a 'show system users' did not show this user online,
the mgd process was still there.)

The root problem is a dead re1, stuck in a reboot loop.

thanks!
