| Hmmm,
|
| Well, I have some requests (like data imports of 50,000 +
| records) and some long string parsing routines, so I think
| setting it down to 2 or 3 would not be appropriate as alot of
| requests might queu up in that time. I have it set at 20 on a
| dual Xeon 1.8 w/ 3 gigs of ram.
|
| I could try lowering it and see if that helps I guess. 10
| requests would be fine, as the server is never really over
| that anyways. And its usually under 3, but as I explained
| there are those occasions where 3 would not be enough
| considering some of the longer requests that are possible.

|
| Really? Wow, I have never seen or heard of that? That must
| kill in a shared hosting environment. Actually, my friend who
| runs an ISP says he's going to stop doing CF hosting because
| they can't keep CF up. I can understand that in a shared
| hosting environment, but on a single site on a single server,
| I should be able to keep it stable I think.
|
| I checked Macromedia's site and actually, I do not have a
| bunch of the latest hot fixes installed. So I'm gonna run
| through that tonight and get that rectified and see if it helps.
|
| When the crash occurs, pages just server up the "unable to
| connect to Jrun Server' page. I do not know what the CPU or
| memory usage was prior to the crash, cause, it was not being logged.
