Description
Some recent changes to the map/reduce code in couchstore appear to be causing a memory leak - see this noop patch off current master which demonstrates the issue: http://review.couchbase.org/#/c/84057/
The following tests FAILED:
|
6 - couchstore-mapreduce-builtin-test (Failed)
|
7 - couchstore-mapreduce-map-test (Failed)
|
8 - couchstore-mapreduce-reduce-test (Failed)
|
9 - couchstore-testapp (Failed)

Example failure (they appear similar):
