Hi Christopher, Thank you for your insights and sorry for a late reply.
This specific issue seemed do be because of limited bandwidth at the data centre and it had now been fixed. We are having some other problem as well, but these seem to come from inefficient modules at the moment and we are investigating at full pace. > What is the JkMount directive(s) that you are trying to undo with > JkUnMount?

It is both cool and weird. :P The reason for 64Gb is basically that when things break down, more ram and cpu delays the problem. We are looking for ways to reduce memory usage. > Up. Grade. We are looking into it, but 7.0.26 seems to be associated with this Ubuntu version. Is it a huge difference? I really don't want to rock this boat any more that absolutely necessary. Again, thank you for your time and insights!
