[chef] Re: Re: EOFError: end of file reached

[Jake Plimack < >]

I was getting an EOFerror a couple weeks ago due to cookbook/cache/optimization files.  I was able to use knife-solve and knife-crawl to narrow down which cookbooks were the problem. (if you run chef-client -o "recipe[base]" - or something you know works, it will complete a chef run, probably).  I also had a spike in erchef's CPU usage on my chef server with the corruption, so you may be able to correlate a commit with your monitoring if you also have this cpu spike.  once you track down the cookbook, knife delete <cookbook> --purge and reupload it.  

Hope this helps.

22:33 <jewart> well, EOFError is just the client saying that the HTTP request was narfed really, so it doesn't know much other than what it was just asking for

22:34 <jewart> which -l debug helps you find

22:34 <Eulipion> right

22:35 <Eulipion> so what gets left of a chef server when u delete a cookbook, but dont purge it?

22:35 <Eulipion> therein lies the culprit

22:36 <jewart> I believe it deletes any files that came with it

22:36 <jewart> when Chef stores data it stores data keyed by the file hash

22:36 <jewart> to dedupe

22:36 <jewart> So if you --purge, any other cookbook that relies on those files would stop working

22:37 <jewart> premature optimization possibly

22:38 <Eulipion> like it not detecting a change?

 

22:38 <jewart> well, let's say you upload cookbooks x, y and z

22:38 <jewart> and they all have a file foo.rb in them

22:38 <jewart> and that's the same file

22:38 <jewart> chef stores them as hashes to dedupe data (which may be a premature optimization that causes other problems but that's a different cat to skin)

22:39 <jewart> so if you remove the cookbook, I think it just removes the records, but if you --purge, it deletes the files

If you ssh this host, and run sudo chef-client by hand, always work?

The chef client is running as crontab, sometimes I got error of “EOFError: end of file reached”, help to check attached email for detail. It’s not occurred every time, 2-3 time per week for 40 nodes running chef-client every half an hour.
