Subject Re: max_document_size limits on hosted services?

Hi, Jens.

Cloudant and Iris Couch run dissimilar software. It's a big clue that
you have problems on both. Either you found a deep bug common to both
(e.g. MochiWeb); or maybe they are independent failures; or maybe door
number three.

You say there is sometimes a 503 and sometimes a drop. Is that across
both services?

Finally, while not doubting your symptoms at all, I must say in my
experience, the "hosting" has very rarely been a contributing factor
to a bug. It's basically CouchDB (or BigCouch) running on an x86_64

Anyway, if you want, contact me off-list and I can set up some pcap
rules for your couch and we can investigate the captures.

whether this is a symptom of hitting a server-side limit on the maximum size of a document

IrisCouch account. Is there some other limit on document size, or known bugs that would cause
a server error with very large JSON documents?
