Troubleshooting Defunct (Zombie) Processes on Linux

At work (LNI) we have a tool which implements a remotely controlled RDMA agent using the OpenFabrics interface. The agent is used for compliance, interoperability, and performance testing. For quite some time weââ¬â¢ve had a problem where sometimes the agent hangs and then after sending SIGINT (ctrl-C or kill) the agent shows up as ââ¬Ådefunctââ¬Â with a Zombie state in the output of ps.
