Mail delivery stops after some time

[RandieM]

Hello there,

First of all, thank you for programming and making maily_herald available to everyone.

I am having this problem, where mail delivery stops on its own. I am not sure if it is after a number of emails sent or after a specific amount of time. My mailing list has around 3300 emails in total, and I have noticed that mail delivery stops after about 2000 emails have been sent out (or appr. after 20 minutes since start of mailing). This has now happened twice in a row. I do not seem to have this problem with shorter mailing lists. If I stop and then re-start the Rails app, then delivery resumes and finishes without further issues.

Processes, like redis, sidekiq and paperboy, seem to be running and I cannot seem to find anything relevant in my logs.

Any ideas?

Many thanks in advance.

Hello @RandieM ,

Thanks for using our gem! Hope you like it so far.

Regarding your problem, could you send us all three logs (sidekiq, paperboy and sidekiq) along with your gemfile? It would help us reproduce this problem.

Cheers!

Hello @ardahaal,

Thanks a lot for your prompt answer and sorry for taking so long to reply.

Unfortunately, I had not redirected the logs for sidekiq and paperboy to a log file and they were supposedly only output to my terminal, while the mailing was being sent off to subscribers. As I was closely monitoring the mailing, I can say with certainty that no error was output, at least not to the terminal.

The last few logged entries looked like this:

Then, after having sent approximately 2000 emails, it "hang" and did not give any more output. Attached you will find the redis log.

Let me know if there is anything else I could check.

Many thanks!

And here is my Gemfile, which I forgot to attach earlier.
