CouchDB 1.6.1 on Windows 08 r2 - os_process_error exit status 1 - view

Question

I have an installation of couchdb which has been working well for a few weeks now. Today it started to throw an os_process_error exit status 1 when attempting to look at any view. The documents in the DB are very small and the views a quite simple. Total DB size is 20mb, largest document is 2mb, i have noticed that the ERL process pegs the CPU at 99%.
I've looked at:
CouchDB delay building index (CouchDB 1.5.0 on Windows Server 2008 R2)
Specific couchdb views suddenly start timing out
I've increased my time out to 50000 seconds, then lowered it to 500 to see if i could find the document which was killing everything but nothing shows up. Stale views still work as well.
Below is the debug error:

Answer 1

I figured this out but I am not sure why it happened. There was a HUGE document 57mb which had been uploaded to the DB but it was not visible in Futon or anywhere else.
I only found it after digging into the debug log further. I could not access the document via a CURL Get. I ended up having to use CURL -X DELETE with the specific revision then a purge to get rid of the document. Soon as the document was deleted everything worked as expected.
