[erlang-questions] Killing a detached application
Wed Feb 27 18:52:15 CET 2008
I've ran across a problem trying to restart an OTP based application
that I thought i had stopped in the past. I started the application
using the following in a bash script:
erl -mnesia dir '"$DB_DIR"' \
-pa $APP_ROOT/ebin $APP_ROOT/deps/ebin \
-sname messenger \
-s message_service \
-boot start_sasl -config $SASL_CONFIG
It started, no problem.
Then later I used erl to remote shell into the application and stop
Checking with regs(). i can see message_service is stopped and
Now, if I try to run the bash script above again, It won't start and
I get a crash_dump that's looks like it's caused by a conflicting
registered name. Interestingly, I can still remote shell into the
erl sname dave -remsh messenger@REDACTED
But the actual OTP application is not running - because i stopped it
earlier. Once I rebooted my machine all worked as expected.
My question is if you start a shell using "sname" and "-detached" how
do you properly/completely stop it? Is the sname held somewhere
different then a registered name?
My goal is to be able to control this from an init.d script.
