I don't know precisely what "report logs with dates and times" (logs, or reports, or both?) the tech support staff has readily available access to, but I suspect you might be thinking they have more readily accessible forensic tools than are actually available to them. Logs, sure! That's kinda like that mechanic again who has access to your car's diagnostics computer which, as everyone who has ever had a difficult to resolve engine issue knows, does not always provide a clear and unambiguous indication of the relevant problem.
I assume those "server reports" you are referring to, are the reports of the panel diagnostic tests - which show high load conditions, but don't help much in determining why the load is high.
Well that is a bit of a different issue then, isn't it? Of course they should "fix it pretty quickly" if "at least one really heavy user" is , in fact, the problem.
With NFS involved, high load numbers might be totally related to that alone, and often are the result of a cluster issue and not at all related to another user's "really heavy use". Again, you are making an assumption about what the source of the problem really is, and are very quick to assume that DH tech support is ignoring the problem when there is a very real, and understandable, possibility that they simply cannot identify the cause of the load condition that existed when you submitted the ticket.
Ok, what I gather from your previous posts in this thread is that you have a problem with your site being unresponsive at some time "every damn day" and that:
Support ignores your tickets
Then "the issue here" is "inability to accept there's a continuing issue and to finally resolve it"
And finally you indicate you believe the that DreamHost "has already tracked the issue to another part of the system (i.e. user who are "at least one really heavy user").
While I don't think your logic is necessarily sound, as I've indicated above, it's apparent that you believe it is, and is seems you think DreamHost is just refusing to deal with a problematic user that is affecting your shared server experience. In the 10 years I've hosted here, I've never seen that to be the case, and I can't imagine that they treat you any differently than they treat me. For that reason, I suspect that there is likely something about your issue that is more complicated for them to deal with than you assume it to be.
I hope this thread doesn't become a reprise of your last "marathon gripe fest" back in Februrary of 2007 (37 posts in several threads on February 25th alone!), and that you can get the matter resolved soon so won't feel "dirty" about displaying your affiliate ad thing on "Captain Blue's Page O' Crap".
Seriously, I'm sure DreamHost staff is not ignoring your support requests and will continue to work toward resolving your problem(s) even while you continue to bash them in these forums for their efforts - that's just the way they roll. Good luck!
