Do not process already processing feed

[arjanfrans]

I am currently having a problem that my monitoring tool is getting a lot of errors; I have a cron job running; that processes the feeds every minute. From what I understand what is happening here; if the feed is already processing, and is then being processed again, then it will throw the The feed is not in a valid state. State is processing exception.

In my opinion this shouldn't really be an exception. Throwing this exception can be avoided by not processing 'already processing' feeds, right?

I believe this can be fixed this way:

• (at plugin repository) Create findReadyToBeProcessed rather than findEnabled which return enabled records in proper state.
• (at server side) Run processing not so frequently

I am aware that running it so frequently doesn't make sense; but I did that since I was still in a testing phase. Anyway, this should be fixed, since it is an exception that shouldn't really happen.
