Description

Not sure if this is a CouchDB or Erlang bug or both. Please, forward to Erland team if appropriate.

What happened:
I've started several thousands of atomic inserts with modified sample php script from http://wiki.apache.org/couchdb/GettingStartedWithPhp
In the middle of insert loop I initiated database compact from localhost:5984/_utils interface.
Several thousands of inserts later CouchDB dumped the following error and terminated:
