Michal Babacek resolved MODCLUSTER-400.
---------------------------------------
Resolution: Cannot Reproduce Bug
I can't reproduce it with mod_clustrer 1.2.10+ any more, EAP 6.4 Beta. I'll reopen the Jira if it ever occurs again.

> One could note that in the moment of fail-over from worker {{jboss-eap-6.3}} to worker {{jboss-eap-6.3-2}}, the original session {{vjZSMs4fZ8j0h+VIQ-GLAz+F}} had been lost and a new one, {{tYnoHJhX73UYrr3QCaUikR9h}} was created.
> If we comment out all the SSL settings and switch to the AJP connector, the failover seems all right though (see the [^hp-ux_error_log-ajp-failover.zip]):

> Note that the session {{hPRQD5FsZUAqZa3ZxRBXIF}} remained the same during the failover, only a new jvmRoute were appended.
> The most bewildering thing is that this behavior is specific to {{hpuxws22Apache B.2.2.15.15 HP-UX Apache-based Web Server}},
> i.e., I've carefully followed the same scenario with the same config on RHEL 6 x86_64, Apache/2.2.22 and the session is kept both with AJP and HTTPS connectors (see [^rhel_error_log-ssl-failover.zip]).
