I am working on a project to migrate all our IPlanet 6.1 SP19 webserver proxies (formerly Sun One) to Apache 2.4, since IPlanet 6.1 does not support TLS 1.2 and IPlanet 7.0 is being EOL. Our backend application servers are Weblogic 9.2 / Weblogic 12c. The IPlanet proxies have performed FLAWLESSLY for over 10 years, despite the product being no longer supported and their WL Plug-in not officially supported with Weblogic 12c. However now that we are trying to use a more supported configuration (self-compiled Apache 2.4.18 running Weblogic Server Plugin 12.1.3) we are constantly seeing these errors, which results in performance degradation for our applications, and in some cases I think maybe even lost data.

We did a network trace and it looks like the Apache plug-in is pre-maturely closing the connection to the WL server, but I can't be certain. We know that our firewall is not responsible. Any ideas ? I thought Apache would work better then Sun One, but this has been the opposite. Is there some fundamental webserver tunable parameter that is so different between out of the box Sun One and out of the box Apache that could be causing this ? --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
