I for one appreciate your efforts!
OT - was asked yesterday during a bus dev call "what is your site
built in/with" that old saw. When I said cold fusion they chuckled.
This from a 26 year old. No matter. He asked what other sites are
built with CF. That old saw. Used to be a list but I am not sure it's
kept up anymore.
The one that came to mind was Bank of America, but there are other big
ones.

To be clear, I wasn’t referring at all to anything about you or
setup Derrick. :-) Still, as you’re saying, yes there are also those
kinds of issues that can cause problems as well. Good that you’ve
isolated a lot of them.
That said, as for your moving to BD, I will argue that when some
have asserted that only another CFML engine was capable of handling
their load, I always wonder if their problem with CF was really what
it appeared to be on the surface. In fact, someone could install a
new engine on the same machine talking to the same DB with the same
load as CF did, and argue that it was better, and I would be willing
to bet that a new install of CF could also have had the same
improvement. Again, too much to get into in this thread, but I can
attest to the situations.
So I’m not knocking the other engines. I’m just saying that
sometimes the moves to them (or off of CFML to some other platform)
could have maybe been avoided by just getting to the root cause of
the problems. There are nearly always discernable explanations, if
one knows where to look and how to connect the dots.
And to be clear, there are indeed many here who can and do just
that, so I’m not saying I’m a superhero. I’m just saying that in
addition to 12 years with CF and 25 in IT, I’ve also focused the
past 3 solely on CF server troubleshooting, and I’ve learned an
awful lot. I’ve had the benefit of learning from many here on this
list. More than that, I’ve been able to make it my day’s work each
day to focus on this stuff, so it’s a unique blessing. I realize why
most can’t do this in their day.
All I’m saying is that I want to help people be more effective in
their trying to understand and resolve CF (or other CFML engine)
problems. The problems (and solutions) are not always what they seem
on the surface. :-) The good news is that there is a lot of info out
there, it’s just a matter of finding the right info for the right
problem—and synthesizing it. I’ll do what I can in coming years to
help with that (the radio show, a planned wiki, and more).

Production server?
Charlie:
I have seen those errors before and would in the past, adjust both
java Vm settings and heap size in the BD admin console, as well as
MySQL settings. I did that over many months a few years back. Using
the same system today.
The settings I use now yielded the best results - no errors, faster
execution times, no crashes, low cpu usage. However....
I do agree with you that there are often many other issues to solve.
In fact, thinking back to our meeting back in 2004 when you helped
me set up BD on my XServe and thus made me a BD fan forever, it was
obvious then that there were other issues to solve and that BD/CF
was not the issue.
Over the past 5 years, BD 6 has proven to be very reliable and
robust and I generate a fair number of page views on a daily basis.
Yesterday, for example, 79,000 CF pages generated - granted 72,000
were spider/crawlers and only 7,000 were user page views. But as far
as the data execution, a page load is a page load. And that does not
include the 10,000 RSS feeds generated on the fly. So...
When I've run into problems in the past, it's generally been either
an SQL statement that I did not think through, or a server issue -
mail problems, FTP break in attempt, etc.,
All that being said, over the pst 5 years, we've taken pains to
simplify the roles of the server itself so that it is not doing 100
various things. DNS, a single mail account, a very few select
number of FTP users, firewall and then web. That's it. No custom
install stuff, very strict clean OS. And with that, the settings I
have used for BD (CF) remain the best for my situation. 4 GB to
MySQL, 2 GB to BD w/1GB heap.
I say "best" because I sleep at night and don't have errors,
excessive CPU or other crazy issues. Perhaps someone could tweak it
more. But it's a proven set up.
