The stalepid utility was developed to facilitate the startup of servers
|
|
that write their process ID to a file and refuse to start if that file
|
|
exists (e.g. when the process was last terminated by an unclean shutdown,
|
|
or simply killed without given the chance to clean up the process ID
|
|
file). The stalepid utility is used to check for and possibly remove
|
|
those stale process ID files. Upon its invocation, stalepid checks for
|
|
the following conditions:
|
|
- the file specified by the pidfile argument exists;
|
|
- it contains a single line, and the line contains a single number;
|
|
- there is no process with the process ID specified in the file, or if
|
|
there is one, it is not named processname.
|
|
|
|
If all those conditions are met, the stalepid utility will remove the
|
|
file specified by the pidfile argument, thus allowing the next invocation
|
|
of the server to proceed normally.
