We're running Tomcat 8.5, currently configured with the following OpenSSL
cipher strings in our SSLHostConfig:
ciphers="HIGH:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!kRSA:!PSK"
However, SSLLabs' server test reports that the following available ciphers are
weak:
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
Eric sent me a copy of the strace (thanks Eric) and while it is
consistent with what has already been observed, it didn't provide any
new information on the socket / file descriptor being closed.
I'd like to suggest running again with the following:
sudo strace -r -f -e trace=network,desc -p

Chris,
I have changed the connector config as below, it has improved the
performance. I want to use this config to support at least 20k concurrent
requests. I have tested this config and there is a delay in the response
and noticed that it's coming from elastic search. I am trying to increase

lol, and there I was feeling ignored :-)
That was the first thing I would have looked at. Is the OS reporting errors
to the JVM writing data or is the JVM not writing the data. Strace will
tell you this quite easily.

The below function (getopts) is working fine Tomcat 8.0.21 but is not working
in Tomcat 9.0.38. We even tried Tomcat 9.0.39 as well and it is not
