[chef] RE: RE: RE: Re: os_process_error in CouchDB

[< >]

I did read somewhere that CouchDB < 1.x.x can be problematic. I should also 
mention that we have since rebuilt our chef-server on Ubuntu 11.10 which 
includes CouchDB 1.0.1. We have no issues, but we are very interested in 
getting to the root cause of this problem, because we are still nervous.

Hi Adam,

couch.log is 125000 lines long, so I'll include the beginning
(http://pastie.org/3602674) and the end (http://pastie.org/3602677).
I'll post to CouchDB's mailing list too.

I have to add to my below description that after I rebuilt the
chef-server, I reloaded all of our cookbooks, roles and databags.

I do believe that Randy has the same issue, although I'm not sure what
version of CouchDB he is using.

Can you show us the full stack trace from CouchDB?

Have you showed it to the folks on the CouchDB list?
