Subject Re: Tomcat3.2+Redhat 7.0+glibc-2.x.x+jdk1.x == stable??

The glibc that RH7 shipped with was beta and very broken - you need to apply their patch set.
Red Hat rushed their 7.0 release, breaking their
convention (major version = new Linux kernel) and a lot of stuff besides. Most of the new
stuff in it is GUI related, and as such you may be
better sticking with 6.2 for server use.

Depending on what your code does, you may get better performance from a green threads VM -
with 1.3 these are starting to go away; you can still
get green threads with the Sun JDK using --classic but I believe it hobbles HotSpot. We still
run 1.2.2 in production and are evaluating the 1.3
VM's for stability.

Like most open source projects, Apache stuff comes from a Unix heritage, and while you can
shoehorn it onto Windows, you will have a much easier
life if you stick with Linux. Just check this newsgroup - 90% of the traffic is "I can't get
x, y or z to work on NT"
