check-ps is a program that runs in the background, periodically executing the 'ps' program and checking its contents against the list of processes in a SysV-style /proc file system. Any processes that appear in /proc and do not appear in the information returned by 'ps' are logged and can even be killed. Any processes that appear in the output of 'ps' and not /proc are also reported (this might be done to give you the impression that syslogd is running when it is not, for example). Restriction: non-extant processes with non-fixed pids reported are not detected but easy for humans to detect.
