Hello Openswan Community.


       We have an application running on centos 7 that is a Tomcat
application which connects to our Mainframe Z/OS CICS and we are using
openswan for that tunnel and sending transactions up through the linux
to mainframe over that tunnel.

       We’ve done numers troubleshooting exercises but concurrency seems
to be an issue for us. So weather its 50/100/200 simultaneous
transactions, we immediately start getting connection refused and
disconnects. However the Mainframe logs and system looks great, and the
linux sar data looks fantastic as well, but nothing we can find is
telling us or helping tell us where the bottleneck is occurring.

        Any ideas?
