Season Pass not working with large libraries

Sonarr version (exact version): 2.0.0.4389

Description of issue:
When i attempt to update all tv series to set them all to ‘all’ monitored or any thing else for that matter, it changes what is displayed but never actually updates the settings for each series/season. This is on 406 series selected, using the select all check box up top.

If i manually select series and use the controls below it will actually update the shows as requested in the drop down boxes. Using the select all it seems to simply change the displayed info, but never actually updates the series.

I tried enabling debug log level, and viewed this after attempting a change all in season pass, but there was nothing displayed on the matter in the logs.

This is something we’ve seen before, but it’s not exactly clear how it’s happening, though it may be related to the size of the payload being sent as selecting a smaller number of series avoids the issue. We have plans to make the payload smaller and hopefully resolve this in a future version.
