Performing robustness check and in system , we have two tomcat workers are set like below. and when connection was broken (intentionally)for one worker , apache hangs and not sending traffic to other working worker. After 90 secs its started sending traffic. During the halt time few requests are failed with 502 error.

Performed the same test with connectiontimeout=5 and results are little different compare to above mentioned. There was no halt seen but no of requests sent to other node is very limited. Throughput was very down for 2 or 3 minutes and later healthy worker picked up the load . Apache should send the traffic to other worker when one worker is down and there would be any delay in traffic.
proxy_hcheck_module (hcmethod=TCP hcinterval=2 hcpasses=1 hcfails=1 connectiontimeout=5) also used in the configuration and there was no different in the above behaviour. Very slow traffic was observed significant time(1 to 3 minutes ) before increasing the load on healthy worker.
Please help me configuring apache in a way that no halt or slowdown in the traffic when one worker connection is broken. Apache should identify and divert the traffic to healthy worker.
