Notification E-Mail all 30 mins

Steps to reproduce

I can't reproduce the steps. It comes from one day to another.

Expected behaviour

When a user (user A) share some folders or files to other users (user B) or to a group (group A), the cronjob send the user B or the members of group A an email notification about the new share.

Actual behaviour

Till yesterday user B and/or group A get the e-mail notification again every 30 mins when the new cronjob start. I must stop the notification service.

Well the problem is, that it fails to send all mails:

Error while running background job (class: OCA\Activity\BackgroundJob\EmailNotification, arguments:
Exception: Swift_TransportException
Message: Connection to localhost:25 Timed Out

Seems like your mail server is dying while sending. I can post you a workaround in some minutes, so it stops the duplication, but you should have a look at the timeout issue.

Can you test https://github.com/nextcloud/activity/pull/52/files please?

Also when you say the email comes every 30 minutes, please note that the cron job should be executed at least every 15 minutes: https://docs.nextcloud.com/server/10/admin_manual/configuration_server/background_jobs_configuration.html#cron

Hey,
yes the cron job start every 15 minutes, but I received the Mail every 30 minutes.

I don't know how I can change the files with git but I changed the files manually.

I started the cron job via sudo -u www-data php -f cron.php and received an email notification with the same content. I do it in 30 minutes again to test if I received the notification again.

During the cron job send the notification I get this message in the Logfiles from Postfix.

Oct 12 12:58:36 srv1 postfix/smtpd[9238]: lost connection after DATA (206 bytes) from localhost[127.0.0.1]
Oct 12 12:58:36 srv1 postfix/smtpd[9238]: disconnect from localhost[127.0.0.1]

Volker

Hey,
here are the new logs. I get the email again but now all users.

are all the "old" entries of people that got a mail still in the activity_mq database table?

I have started the cron job for 10 minutes again and I don't received an notification email.
The table activity_mq is empty.

Is now the problem solved or I must check my mail server to solve the problem?

Volker

No,seems all good then, thanks for testing.
