Ok, I will try rr module from 4.0 branch and if it won't help from
master branch.
Have you tried the latest code on the 4.0 branch as I
am sure there
are fixes that have been made since the last release?
Also, if using WebSockets I do strongly recommend you try Git master
if you have any problems. There may well be fixes there that haven't
been back-ported to the 4.0 branch yet.

Peter
