this was clearly a one-time incident(and I'm fairly sure there was a
network issue too) - we only have two jails on alderaan at all and it is
more than fast enough to handle the wiki and git.

shows pretty nicely that after I killed the two rough processes load
diminished - what is more interesting here actually why our current
monitoring failed to detect that situation which is what I'm current
investigating ...
