wohali commented on issue #745: Replication with attachments never completes, {mp_parser_died,noproc} error
URL: https://github.com/apache/couchdb/issues/745#issuecomment-369447881
 
 
   So in testing with a client, this no longer hangs/crashes/eats all the RAM, but it does still cause an issue where a too-large request body fails to transmit an attachment. The replicator thinks it HAS successfully transferred the document, and declares replication successful. A subsequent attempt to GET the document results in a 404.
   
   Here is a censored excerpt from the logfile of the situation:
