sklassen opened a new issue #1008: Time-out issue when running native erlang views in 2.x on 
URL: https://github.com/apache/couchdb/issues/1008
 
 
   
   I am seeing a time out when indexing a view written in native erlang. The erlang view works with 1.6.x for databases of any size; the view also works on 2.x, for database with fewer records or smaller documents. Ran against a database with many large(ish) documents, I see the following error:
   
   [error] 2017-11-17T03:00:11.072015Z couchdb@localhost <0.12.1196> 19a93c5b89 rexi_server throw:{timeout,{gen_server,call,[<0.9106.1195>,{prompt,[...]}}]}]}]}} [{couch_mrview_util,get_view,4,[{file,"src/couch_mrview_util.erl"},{line,56}]},{couch_mrview,query_view,6,[{file,"src/couch_mrview.erl"},{line,244}]},{rexi_server,init_p,3,[{file,"src/rexi_server.erl"},{line,139}]}]
   
   If you latter try to call a view that failed due to time out, you get a second error:
   
   [error] 2017-11-17T05:01:27.670419Z couchdb@localhost <0.26156.1198> d00b01bc7d rexi_server exit:timeout [{rexi,init_stream,1,[{file,"src/rexi.erl"},{line,256}]},{rexi,stream2,3,[{file,"src/rexi.erl"},{line,204}]},{fabric_rpc,view_cb,2,[{file,"src/fabric_rpc.erl"},{line,286}]},{couch_mrview,map_fold,3,[{file,"src/couch_mrview.erl"},{line,503}]},{couch_mrview_util,fold_fun,4,[{file,"src/couch_mrview_util.erl"},{line,360}]},{couch_btree,stream_kv_node2,8,[{file,"src/couch_btree.erl"},{line,783}]},{couch_btree,stream_kp_node,7,[{file,"src/couch_btree.erl"},{line,710}]},{couch_btree,fold,4,[{file,"src/couch_btree.erl"},{line,217}]}]
   
   I suspect the gen_server timeout needs to be extended. With multiple nodes, some index tasked might be preempted and thus timing out. 
   
   I used the Ubuntu package couchdb 2.1.1-1 on xenial; I also replicated the same error on a an earlier 2.0 version running under snap.
