A moderator closed a question of mine as a duplicate despite it not being a duplicate (the circumstances and the question are different, he claimed it was a duplicate of a general FAQ-style question). He also implied twice in comments that I was somehow withholding information, and generally just didn't seem to grasp the question I was asking.
I then posted another question (written better than the original, which admittedly was worded a bit vaguely) asking the question more clearly and explaining why it is not a duplicate of the existing answer. A few minutes later, the same moderator deleted it without explanation.
To repeat important details: I am asking about why a clean install being used only for an incoming SSH tunnel would be showing such high memory usage coupled with a regular failure of the tunnel. The VPS provider appears to be counting cache memory in their totals, adding up to 2GB in the VPS control panel while
ps show nothing out of line. This would imply caching, but I can't figure out what's actually being cached as there's nothing else running and the OS doesn't even take up that much on disk. The high memory usage started at the same time the ssh tunnel started failing, both without any configuration changes, so they may be related; they are also not normal behavior, as the machine ran without either issue for several months.
The moderator who targeted these questions doesn't seem to understand this, as he appears to think that this is normal behavior by simply referring to a general FAQ about memory.
