Description

Couchdb 0.11.0 replication tasks fails with the below after working for everything from a few minutes to an hour. The below replication is of the type

{"source":"http://127.0.0.1:5984/node-metrics", "target":"http://1.2.3.4:5984/node-metrics", "continuous":true}

and the node-metrics database exist on both machines.

The database is periodically compacted which, and I'm speculating here, could be a contributing factor to the crash.

Kind regards,
Fredrik Widlund
