Is Interchange in PreFork, or fork-on-demand? What is the MaxServers setting?

Appears to be fork-on-demand. There's only one IC running, unless it's serving a request. Hrm.....it's in "low" traffic mode, which at the moment sets MaxServers to 5. I don't know whether i've ever seen it busy enough to need 5 copies running...but considering the machine's serving 15 catalogs...maybe turning it up isn't too bad an idea.

Another box, which seems to be running great, has MaxServers set to 0. As far as i remember, i didn't do that (i've never had a reason to tweak those settings, as until now they've always just worked). I assume that unlimits MaxServers -- which, although it works a lot better than the current state of things, doesn't seem too safe to me.

Going to look at changing the MaxServers setting, and probably turn on PreFork as it sounds like it'd help speed things up a bit.

Personally I wouldn't mess with PreFork yet ... one thing at a time. :)

Try setting MaxServers higher, or to 0. Setting it to 0 can stop some weird signals problems. It does run the risk of a runaway, but if you don't have infinite loops in your code somewhere it's unlikely in my experience.
