Problems with Oracle, Apache, mod_ssl and firewalls - hang

Hi,

We have an Apache server as supplied by Oracle (1.3.19), serving both static html and mod_plsql pages.

When the system is accessed via SSL and the Internet, it will tend to hang after a relatively short time - especially if two people access at the same time. This is seen at the browser as a page that simply fails to arrive, there is no standard 'Page could not be found' type message.

A network sniffer seems to show that there is some continuing network traffic, but the Apache error_log does not show activity.

If the system is accessed without SSL but still via the Internet then there appears to be no problems and the system runs a lot faster than SSL + Internet.

If the system is accessed with SSL but internally so avoiding the Internet then there also appears to be no problems and the system runs faster than SSL + Internet.

Our servers are running NT4 SP6.

Our firewall is Checkpoint NG running on Solaris (although we also swapped in a Nokia firewall running Checkpoint 4.1 which had the same results).

Any thoughts on what might be occurring, what we should be looking at next?
