For that you can try an 'expect' script like this:
#!/usr/local/bin/expect -f
set prompt "(%|#|\\$) $" ;# default prompt
catch {set prompt $env(EXPECT_PROMPT)}
set timeout 5
spawn $env(SHELL)
expect -re $prompt
send -- "telnet localhost 1720\r"
set date [exec date]
expect {
-re ".*Unable to connect to remote host"
{
send_user "\rGK not running! Initiating restart. $date\r"
send -- "/usr/local/bin/gnugk -c /usr/local/etc/gnugk.ini -ttt -o /var/log/gnugk\r"
expect -re ".*Listen on"
send -- "\r"
exit
} -re ".*Connected to" {
send_user "\rGK is running at $date\r"
exit
}
}
You will have to modify the path to 'expect' and to your 'gnugk' location. And you need to install expect first.
If you use mysql or postgresql you can try a similar mechanism to check if their ports are answering and restart them also if needed.

As simple shell script which you can run after 1/5 minute interval using cron job. May be someone can write a better shell script , I am not an expert in writing shell scripts but this does work.
#!/bin/sh
value=`/bin/ps -e|grep gnugk`
if [ ! "$value" ]; then
/sbin/service gk restart
