Subject Re: CouchDB crashing at random times
Date Mon, 26 Aug 2013 17:15:49 GMT
Hi Dave,

Your suggestion certainly worked. I changed the 'delayed_commits' to false
in the config, and I didn't see the crash (and subsequent connection
refused error).

What are the implications of setting 'delayed_commits' to false? Or better
yet, what does setting 'delayed_commits' to true and false do?

Thank you so much for your help, BTW!
