Have you got a solution from TAC please?
We have same error message in /var/log/httpd2_error_log after R.77.30 node joined cluster.
tcpdump shows 3-WAY handshake OK and then nothing happened.
different browsers show blank screen, none of tcl scripts are not starting.
we have restarted httpd daemon - same issue.
