When the server crashes, hlds_run attempts to create a bug report before restarting the server. Instead, it hangs. The reason for this is tries to cat the pidfile in the following lines.
191 # check to see if a core was dumped
192 if test -f core ; then
193 CORE="core"
194 elif test -f core.`cat $PID_FILE`; then
195 CORE=core.`cat $PID_FILE`
196 elif test -f "$HL.core" ; then
197 CORE="$HL.core"
198 fi
The problem is that PID_FILE is not always defined (despite the script tries to ensure that). When it is unset, cat ends up being called without arguments so it reads from the standard input, effectively hanging the script. Killing the cat process lets the script advance.
I'd generally suggest to revise the script by modern standards and use shellcheck to uncover potential issues.
