Reporter: Adam L Levine
I can't replicate this via just command line, but can repeatedly using gradle.
I can't find what's different about the gradle launch vs running it by hand.
FWIW, there are 2 parallel folder structures: one for the gradle scripts, one
for DS.
I've pasted the console output and the relevant gradle script.
{*}Overview{*}:
# I start DS via a gradle task
# I can verify the PID matches the ID stored in apacheds.pid
# I run the start task again
# DS starts a 2nd process, but fails and exits because the listening port is
already bound by the first process
# The ID stored in apacheds.pid now contains the PID of the 2nd process.
# stop/status will now fail because the PID doesn't match
