gitlab-workhorse.socket failed (111: Connection refused) while connecting to upstream
after update to gitlab-version 8.7 gitlab-shell v2.7.1 gitlab-workhorse v0.7.0, our website is always crashed because of gitlab-workhorse.socket failed (111: Connection refused) while connecting to upstream
. there are many these errors in nginx/error.log.
and we have to restart the gitlab service to fix that, but after some times, it crashed again, we have no clues to fix that, could someone provide some clues?
can high concurrence environment lead that?
