Subject [jira] [Commented] (COUCHDB-2304) changes_reader_died when trying to replicate 25mb DB locally
Date Tue, 26 Aug 2014 05:58:58 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-2304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14110332#comment-14110332
] 

Alexander Shorin commented on COUCHDB-2304:
-------------------------------------------

It shouldn't be and IIRC even if it's too big, query server fails with different error. First
just make sure that query server works and if you feel that big docs are the problem, try
to increase stack size via couchjs -S argument.
