Importing large content with Feeds and cron I've used the migrate module in the past, it's great to import large amounts of content but it's pretty complex.
This time I'm trying Feeds and Feeds_SQL to import from a mysql tables. It imports fine when I kick it off with the import UI. However it will give an Ajax error after importing a few hundred records.

I try to import using cron. That's where it gets confusing to me:

I select "periodic import" -> "as often as possible", uncheck "import on submission" and check "process in the background".



I then start the import using the UI, it imports some nodes and then stops.

When I manually run "feeds_cron" nothing happens. When I manually run "job_scheduler_con" it showed "Finished processing scheduled jobs (0 sec s, 1 total, 0 failed)." in teh logs and imported more records (but not all).
When I run it again it shows "Finished processing scheduled jobs (0 sec s, 0 total, 0 failed)." and nothing gets imported.

Do I have the correct settings? How are the "periodic import" setting and the "feeds cron" and "job scheduler cron" related?

Is there a setting somewhere that controls how many nodes are processed each time?
Are you running the actual site cron? If not, run it.

As for the Ajax errors when running a manual import, are you sure that it isn't continuing to import despite these? My large imports will time out the browser connection when I manually import in feeds, but they will actually still continue to process.

Also, could you try changing your setting from "As often as possible" to "Every 30 minutes", to ensure the crons aren't running over each other?
