For example, one developer makes a review comment at 12:21, the notification was received at 16:45 !
EDIT: it seems that our mail server is sometimes holding some of swarm mails. Anyway, in this example, swarm apparently waited about 19 minutes before sending the notification which is rather strange.
For the context, we never had any issue with our email server. Our swarm server is configured with three workers {"tasks":0,"futureTasks":0,"workers":3,"maxWorkers":3,"workerLifetime":"595s"} and we are using the OVA distribution (2014/3/958056 apt-get upgraded). The main swarm features are working fine, no noticeable delays in browsing code, creating reviews...etc.
Note that our logs contain several lines of the following error, which is odd because we did not customize the email template:
2015-02-10T01:19:51+00:00 ERR (3): Cannot send mail. No valid templates specified.
Our email configuration is:
'notifications' => array( 'opt_in_review_path' => '//swarm', 'disable_change_emails' => true, 'honor_p4_reviews' => false, ),
Any idea ?
