We can use different ways to add the init script to a build. For example we can use the command-line option -I or --init-script, place the script in the init.d directory of our GRADLE_HOME directory or USER_HOME/.gradle directory or place a file init.gradle in our USER_HOME/.gradle directory.

Does Tomcat Bite More Than It Can Chew?

This is an interesting blog post for me, since its about the root cause for an issue we saw with Tomcat back in May 2011, which remained unresolved. Under high concurrency and load, Tomcat would reset (i.e. TCP level RST) client connections, without refusing to accept them - as one would expect.
