Is there any reason why Tomcat running under the JSVC daemon using the
Apache Portable Runtime for SSL would act erratically to TCP health checks?
We are using a Juniper DX for load balancing that uses TCP health checks to
port 443 of a Tomcat instance in order to keep the machine in the forwarding
cluster. However, whenever the health check comes in, the logs generated by
Tomcat's AccessLogValve show them to be malformed HTTP requests. My
networking colleagues and the Juniper engineer confirm that it is sending
plain TCP health checks; nothing fancy. As you can see in the logs below,
Tomcat states the TCP health check is malformed HTTP request. Any thoughts?
Sincerely grateful for any assistance,
Andrew
