CouchDB crashed Erland
----------------------

                 Key: COUCHDB-78
                 URL: https://issues.apache.org/jira/browse/COUCHDB-78
             Project: CouchDB
          Issue Type: Bug
          Components: Database Core
    Affects Versions: 0.8
         Environment: Linux 2.6.25.4-30.fc9.i686 #1 SMP Wed May 21 18:12:35 EDT 2008 i686 i686 i386 GNU/Linux

            Reporter: Sergey Kurtsev


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:
