GitLab

Created by: CrossVR

If the Mailroom can't connect to the mailserver due to an SSL error it will keep attempting to connect to it going so far as to dedicate a CPU core to the task of banging the mailserver.

To be precise, the command /opt/gitlab/embedded/bin/ruby /opt/gitlab/embedded/bin/bundle exec mail_room -c /var/opt/gitlab/gitlab-rails/etc/mail_room.yml is using 100% CPU.

My system is Ubuntu Server 14.04 and I am using the omnibus distribution of GitLab.

Here is an excerpt from my mailroom log file:
