Description:
Process monitoring daemon
A bug or malicious attacks to machine can lock up a process, leading to a deadlock or an unexpected condition. For example: an Apache httpd with mod_(php|perl|lua|your_preferred_script_language) running a bad script. When the monitored process locks up, the watchcat helps killing him. It is the best thing to do.
