and in my environment, I have:
python script invoke bash script, and then invoke karaf client with commands.
in the bash scripts, code like below:
su - $KARAF_USER_NAME -c "$KARAF_BIN_DIR/start"
result=`su - $KARAF_USER_NAME -c "$KARAF_BIN_DIR/client -u karaf -p karaf
version 2>&1"`
sometimes it's hanging for ever here.

it's easy to reproduce it.

Hi [~wenjie_sun1979],
Is it easy for you to reproduce it? What's your env?
I've tried 100 times on my machine but can't reproduce this issue anyway.
Thanks
Freeman
