[Moabusers] msrvctl

In our attempts to find an alternate way to create a system-wide
reservation we have been unable to reproduce your problem.

Would it be possible for you to run the following diagnostics and send us
the moab.log?

mschedctl -s
changeparam LOGLEVEL 8
<your_mrsvctl_command_that_fails>
changeparam LOGLEVEL <previous_log_level>
mschedctl -r

This will help us figure out why the command is failing in the first place.

Just for our own records, which patch version of Moab are you using?

Thanks,

- Douglas
