querkmachine Please try adding the following line to supervisor.conf at the beginning of the environment settings (just above RAILS_ENV) for program:puma
and program:sidekiq
(ie you will add the line in 2 different places):
LD_PRELOAD=/usr/lib64/libjemalloc.so.1,
After you've modified the file, stop the app then kill supervisor like so:
pkill -f supervisor
... then restart the app.
