I am running Ubuntu 12.04.3 LTS
when the users try to access the application to login they receive this message:
Service Temporarily Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
when I login to the server i grep for the process and see that it is running but when i try to start it, it does not restart unless i issue kill -9 on the pid then restart it and it is successful. I don't know when the application gets hung but i want to run strace on the pid so if it does hang a script will kill the pid and restart the application.

courierlogger
COURIERLOGGER(1) Double Precision, Inc. COURIERLOGGER(1)
NAME
courierlogger - Courier syslog wrapper
SYNOPSIS
courierlogger [-name=title] [-facility=subsystem] [-pid=filename] [-user=user] [-group=group] [-droproot]
[[[-respawn] [-start] program [argument...]] | [-stop] | [-restart]]
DESCRIPTION
courierlogger is a wrapper that captures another process's error messages, and forwards them to the system logging facility, "syslog".
There are two ways to use courierlogger:
1. Use the shell to pipe another command's standard error, and/or its standard output, to courierlogger's standard input.
2. Alternatively, courierlogger itself can start another process, and arrange to have its standard error captured.
In either case, each read line of text is sent as a syslog message.
OPTIONS
-name=title
Use title for sending messages to syslog. title should be the application's name.
-facility=subsystem
Use subsystem for classifying messages. Your syslog facility uses subsystem to determine which log messages are recorded in which log
files. The currently defined subsystems are:
o auth
o authpriv
o console
o cron
o daemon
o ftp
o kern
o lpr
o mail
o news
o security
o user
o uucp
o local0
o local1
o local2
o local3
o local4
o local5
o local6
o local7
Note
Not all of the above facility names are implemented on every system. Check your system's syslog documentation for information on
which facility names are allowed, and which log files record the corresponding messages for each facility.
-pid=filename
Save courierlogger's process ID in filename. The -pid option is required when -start, -stop, -restart are given. If -pid is given
without any of these, -start is assumed.
-start
Run as a daemon. The pid option is required. courierlogger will quietly terminate if another courierlogger process is already running.
This is used to make sure that only one instance of program is running at the same time. Specify a different filename with pid to start
a second copy of program.
-respawn
Restart program if it terminates. Normally courierlogger itself will terminate when program finishes running. Use respawn to restart it
instead.
-restart
Send a SIGHUP signal to the courierlogger process (as determined by examining the contents of the file specified by pid), which will in
turn send a SIGHUP to its child program. Does nothing if courierlogger is not running.
Note
program must be originally started with the respawn option if sending it a SIGHUP causes it to terminate.
The same thing may be accomplished by sending SIGHUP to courierlogger itself.
-stop
Send a SIGTERM signal to courierlogger, which in turn forwards it on to program. If program does not terminate in 8 seconds, kill it
with SIGKILL.
-user=user, -group=group
If running as root, change credentials to the given user and/or group, which may be given as names or numeric ids.
When running a child program, it is started before privileges are dropped (unless the -droproot option is also given). This gives a
means of starting a child as root so it can bind to a privileged port, but still have courierlogger run as a non-root user. For the
-stop and -restart options to work, you should configure the child program to drop its privileges to the same userid too.
-droproot
Drop root privileges before starting the child process. The -user and -group options specify the non-privileges userid and groupid.
Without the -droproot option the child process remains a root process, and only the parent courierlogger process drops root privileges.
program [ argument ] ...
If a program is given program will be started as a child process of courierlogger, capturing its standard error. Otherwise,
courierlogger reads message from standard input, and automatically terminates when standard input is closed.
