I am using web applications in production with 1.10.2+ZHTTPserver under RH Linux 5.2

What can I do to have Zope s own server work continuously, without manual re-starts every day?

Switch to ZServer. Really. ZopeHTTPServer is, um, a tad flaky. ZServer is very very nice, and has been rock solid for me for a few weeks of solid(ish) use now.

This is basically the best answer... we're not planning to make any further changes/additions/fixes to ZopeHTTPServer (which was used instead of Apache in early releases), and it will most likely "go away" within a few releases. It's just a hacked up version of the BaseHTTPServer that comes with Python. It's very slow, though functional. ZServer is probably your best bet, unless you need something that Apache can provide---i.e. SSL, etc. Chris
