Complexity: High
Steps to Reproduce: h3. How to reproduce
 # Configure AS7 with HTTPS connector as in [^JBPAPP-9493-reproduced-with-m_c-1.2.3.Final.zip]
 # Configure Httpd + Mod_cluster with SSL as in [^JBPAPP-9493-reproduced-with-m_c-1.2.3.Final.zip]
 # Start httpd
 # Start AS7
 # Send a request, e.g. like:
 {noformat}
curl https://localhost:8888/SessionTest/session --cert /home/mbabacek/EAP6/Client/client.crt --key /home/mbabacek/EAP6/Client/client.key --cacert /home/mbabacek/EAP6/Client/myca.crt --insecure -c originally_empty_cookiefile.txt -b originally_empty_cookiefile.txt 2> /dev/null
 {noformat}
 # Optionally, wait ~10 minutes. (!) You might start to having errors even without this request free wait period.
 # Sned another request & get an error
 # Eventually, after *STATUS* message is received, you will get correct HTTP 200 again.

(i) *Note:* As soon as STATUS message is received, it picks up again...
