Hi All,

I have a rocks 6.2 cluster running centos 6.6. It has been working fine, but \
recently, I added a new user and his jobs would not run. It turns out his account had \
not appeared in /etc/passwd on any of the nodes despite me running rocks sync users \
without errors as below:

make: Leaving directory `/var/411'

But the logs contain lots of messages like the following:

Jul 27 17:39:43 compute-0-8 411-alert-handler[13333]: Error: \
http://10.1.1.1:372/411.d/etc.auto..master updating Could not get file \
'http://10.1.1.1:372/411.d/etc.auto..master': 400 Bad

So I set the nodes to rebuild on boot and rebooted a node. On coming up, the node had \
no user accounts at all. If I run 411get as below, I get the following error, \
--verbose does not provide any more information.

411get --all
Error: Could not get file 'http://10.1.1.1:372/411.d//': 400 Bad

I'm guessing something has gone wrong with the 411 service on the server. Http is \
running, I have restarted everything I can think of and rebooted the head node. I \
have run some updates on the head node, which I think may be the cause of the \
problem. Can someone tell me some useful diagnostics to work out what is wrong.

Thanks for any help,
Rhys
