Description

I have a Bot written in C# running well enough on Mono. It works OK on dev.tools.wmflabs.org and on login.tools.wmflabs.org but fails when started with jsub. I think the mono version is different on the two platforms. I think the mono version should be the same for both environments, no? (BTW they are both q bit old' current version is 4.6.1.5

mono v3 on dev machine:

You forgot to specify the correct distribution for jsub. Leaving it unspecified defaults to precise, which is deprecated and will have everything on older versions. The login hosts run trusty:

krenair@tools-bastion-03:~$ jsub -l release=trusty mono --version

This should change soon, https://wikitech.wikimedia.org/wiki/Tools_Precise_deprecation looks outdated
