use of sys-proctable proved to be unstable in check-procs

I first noticed that if you passed in a user it would break the check because sys-proctable does not support the concept of user.

After running this for a couple days it proved to send many false alerts. sys/proctable is doing different IO related events and when it gets to IO.foreach("/proc/#{file}/status") do |line| it's making the check fail when it can't find a pid that has changed/disappeared

A chat in irc with zdunn verified that they are having the same issue with it.

It's my belief this needs to be rolled back.
