I assume that I need to clean up my processes when the build is being stopped, but I don't know exactly what happens when the stop occurs. How does bamboo implement the task stopping? Does it send the child process a signal? If so, which signal is it?
I don't know the exact mechanisms Bamboo uses when you stop a build, but we had to workaround the orphan process problem by creating an "orphan killer" daemon on the machine that periodically looked for Bamboo-owned processes with a parent PID of 1.
