chef server returned 500 internal server error when uploading cookbooks

https://tickets.opscode.com/browse/CHEF-5277
someone else is also seeing this.

another helpful bug report:
https://tickets.opscode.com/browse/CHEF-4504

it seems to be fixed in chef server 11.1.
I will write a patch setting the concurrency to 1 to work around it before we upgrade chef-server to R11 and up.
