[one-users] error while running 1.4beta2

[Stefan Freitag]

Hello Michael,

maybe a stupid question... is ruby installed on the three compute nodes?

I ask becaus of the lines

> Wed Nov 11 12:52:41 2009 [InM][I]: STDERR follows.
> Wed Nov 11 12:52:41 2009 [InM][I]: /usr/bin/env: ruby: No such file or

As far as I know ONE uses a mix of sh and ruby scripts to collect the
monitoring information on the compute nodes.

Kind regards
Stefan
