Sometimes not searching/downloading episodes

[dgcurtis]

I’ve had this issue for a few months now where Sonarr will seem to randomly not download an episode for a show. For example, if I have 5 shows for one day, 4 out of the 5 will be found and download. If I click a manual search for the missing episode, it will find and download it.

I checked this morning and sonarr hadn’t been downloading anything since Wednesday. According to the logs there were no valid indexers. I am using 6 indexers and I know at least half of them were working fine. I’ve had to babysit Sonarr quite a bit due to this.

It seems like Sonarr doesn’t recover at all without a restart if anything happens to a dependent service (like dns or networking). Last week, I had an issue where the server that Sonarr runs on didn’t have a proper dns server specified due to NetworkManager sucking. I put in the dns servers in resolv.conf but I had to restart Sonarr. I’ve seen issues in the past where I’ve done an update to my router while Sonarr was searching and the episodes it was searching for at that time will never be downloaded unless I do a manual search.

My questions are:

• Is there a quick way to force Sonarr to automatically search for missing episodes of a current series/season?
• How often does Sonarr check for missing new episodes?
• Is there a way to be notified if Sonarr isn’t downloading anything or if it’s missed a current shows episode after x amount of time?

Thanks!

Wanted: Missing? The Calendar will also show whats missing.

How often does Sonarr check for missing new episodes?

It doesn’t. https://github.com/Sonarr/Sonarr/wiki/FAQ#how-does-sonarr-find-episodes

No, but you could use the Sonarr API to build something.

For all the time I’ve been using sonarr, I’ve never even looked at the Wanted section. Amazing.

So regarding the rss feeds: does that mean that theoretically if an indexer happened to get more than 100 or so updates since the last rss sync that sonarr could miss an episode?

I’ll look into the API and see about scripting something.

Thanks!

Its possible, but that also depends on the indexer’s support for paging as Sonarr attempts to handle that scenario by paging the RSS feed back as far as it can (also helps when Sonarr isn’t running for a period of time).
