[jira] Commented: (COUCHDB-32) map function timeout
Posted by "Derek Haas (JIRA)" <ji...@apache.org>.

Derek Haas commented on COUCHDB-32:
-----------------------------------
This is most likely because there is a hardcoded 5 second timeout per document defined for the query servers. src/couchdb/couch_query_servers.erl. If you want a quick fix, go into src/couchdb/couch_query_servers.erl, and at line 25 you'll see the timeout() function...you can up that value and recompile to be less likely to get a timeout error.

Benoit Chesneau commented on COUCHDB-32:
----------------------------------------
make more tests tomorrow. I can reproduce this issue on freebsd.
In fact when I do a simple view :
function(doc) {
map(null, doc);
]
it timeout (on 229 results)
when I specify id :
function(doc) {
if (doc._id == 'goodid')
map(doc._id, doc);
}
it work.
is there someting to do about such timeout ?
