java - bash script issue launching programs -

-

i have bash script executed when aws ec2 ubuntu instance boots, via aws server launch configuration (which bash script) using following command 

sudo -u ubuntu /vagrant/test/startall.sh

the issue i'm seeing java programs don't run if they're last entry in bash script, run fine if not last entry. i'm bit stumped why it's happening.

here's bash script...

startall.sh

#!/bin/bash  # set -x  brokersrvdir="/vagrant/test/ppp" meetingsrvdir="/vagrant/test/clone" notifysrvdir="/vagrant/test/notification/production/notificationsrv" workerdir="/vagrant/test/ppp/production/ppworker2"  #( cd $workerdir &&  { make runworker >>log/out.txt 2>&1 & } )  ( cd $brokersrvdir && { ./ppp_broker >>log/out.txt 2>&1 & } )  ( cd $notifysrvdir && { make runnotify >>log/out.txt 2>&1 & } )  ( cd $meetingsrvdir && { ./meetingsrv > /dev/null 2>>log/out.txt & } )  ( cd $workerdir &&  { make runworker >>log/out.txt 2>&1 & } )  #( sleep 10s && cd $brokersrvdir && { ./ppp_broker >>log/out.txt 2>&1 & } )

ppp_broker , meetingsrv c executables
make runworker , make runnotify make calls run java programs

here's makefile worker java program

makefile

dlibs=-lzmq -lczmq ldflags= cflags=-ddebug cpflag=-cp /usr/local/share/java/*:. cpflagdb=-cp /usr/local/share/java/*:. -xx:+heapdumponoutofmemoryerror -xx:errorfile=log/hs_err_pid_%p.log cpflagp=-cp /usr/local/share/java/*:. -  jflags = -g javac=javac sources = $(wildcard *.java) classes = $(sources:.java=.class)  all: $(classes)  clean :         rm -f *.class  %.class : %.java         #export ld_library_path=$(ld_library_path):/usr/local/lib/*           #export classpath=$(classpath):/usr/local/share/java/*:.          $(javac) $(jflags) $(cpflag) $<  .oneshell: runworker :         export ld_library_path=$(ld_library_path):/usr/local/lib/*         export classpath=$(classpath):/usr/local/share/java/*:.         java $(cpflagdb) -djava.library.path=/usr/local/lib/ ppworker2

update: set x output

ubuntu@ip-xxxx:/vagrant/test$ /vagrant/test/startall.sh  + brokersrvdir=/vagrant/test/ppp + meetingsrvdir=/vagrant/test/clone + notifysrvdir=/vagrant/test/notification/production/notificationsrv + workerdir=/vagrant/test/ppp/production/ppworker2 + cd /vagrant/test/ppp + cd /vagrant/test/notification/production/notificationsrv + ./ppp_broker + cd /vagrant/test/clone + make runnotify + cd /vagrant/test/ppp/production/ppworker2 + ./meetingsrv ubuntu@ip-xxxx:/vagrant/test$ + make runworker

output ps after running above:

ubuntu@ip-xxxx:/vagrant/test$ ps -ef | grep make ubuntu    2104     1  0 18:06 pts/0    00:00:00 make runnotify ubuntu    2144  1479  0 18:06 pts/0    00:00:00 grep --color=auto make

so bash script executes make call according set x, it's not running.

as per comment, spun new ec2 instance , works. i'll put down ec2 weirdness now, if happens again i'll dig deeper. thanks!
