Pretty much indefinitely, barring disasters such as hardware failures. Apache
on our main server was last restarted Oct. 7 of last year. It hosts a large
LAMP application, and doesn't use over 128MB (the db is on a separate box).
We have another machine, that serves an older product that 'just runs', where
apache hasn't been restarted since June of last year--that box has over 400
days of uptime. It hosts a java/mysql application with resin and mysql on
the same machine. It stays just under 500MB total.
For linux, I'd say os_uptime can easily approach infinity for all practical
purposes. And, from experience, I'd say apache_on_linux can also approach

For windows, os_uptime is not predictable. Recent versions have massively
improved on this, but there are still corner cases where stability gets a
huge shot in the arm. Worse, IMO, these seem to be getting harder to
predict. As for apache_on_windows, the apache core itself is very stable.
Several developers here run apache on windows and we don't have any
complaints. There may be some extensions that have issues that reduce the
stability. Perhaps the jboss connector is one of these.

I admin that I am not very familiar with jboss, but I should think hardly any.
If it's caching the static data then it will use enough for the cached
content, but I wouldn't think a connection to jboss should consume an
inordinate amount of resources. If connections are lingering, then yes, some
resources may be leaking and require a restart. A 'graceful' restart should
clean that up for you though.
