Hi,

Running map-reduce when deleting the record causing the
bad_utf8_character_code
error. I mean doing both things simultaneously causing the error

Here is the traceback

   Error running MapReduce operation. Headers: {'content-length':
'1312', 'server': 'MochiWeb/1.1 WebMachine/1.10.0 (never breaks eye
contact)', 'connection': 'close', 'date': 'Mon, 20 Oct 2014 18:23:08
GMT', 'content-type': 'text/html', 'http_code': 500} Body:

   [{file,"src/webmachine_resource.erl"},\n

{line,186}]}]}}</pre><P><HR><ADDRESS>mochiweb+webmachine web

I have observed that, every time I do both things simultaneously casing the
error. But later on after a while map-reduce query is working fine.
​Is this mean, can't I run the map-reduce queries while deleting keys from
other client?​
