NAME
pprotectd —
daemon which protect processes from killing by the kernel when
memory is exhausted
SYNOPSIS
pprotectd |
[-n] [-d
debug level] [-l
logfile] [-t
timeout] -F pidfile1,
pidfile2, ... |
DESCRIPTION
Thepprotectd utility sets the P_PROTECTED flag for each
PID from pidfiles that list as an argument. If all given pidfiles exist and
the P_PROTECTED flag is set successfully for each PID, daemon blocks on
kevent(2)
and will wait untill some process becomes terminated. When some process has
terminated, the pprotectd wakes up and gets a new PID
from pidfile, then pprotectd sets the P_PROTECTED flag
for it. If any given pidfile does not exist, the
pprotectd will retry to read it after timeout.
The options are as follows:
-ddebug level- Set debug level (0 - off, 1 - errors, 2 - warnings, 3 - debug). The default is 1.
-Fpidfile1, pidfile2, ...- List of pidfiles that contain PIDs for protection.
-llogfile- Set filename for log messages. If argument equals syslog, daemon log messages will be logged via syslog(3). The default is syslog.
-n- Do not daemonize.
-ttimeout- Set timeout in seconds. The default is 10.
