Replication renders CouchDB unresponsive.
-----------------------------------------
Key: COUCHDB-197
URL: https://issues.apache.org/jira/browse/COUCHDB-197
Project: CouchDB
Issue Type: Bug
Components: Database Core
Reporter: Maximillian Dornseif
I am quite sure this is not the same issue as in COUCHDB-193.
Im trying to replicte a somewhat big database
{"doc_count":541394,"doc_del_count":265692,"update_seq":2118390,"purge_seq":0,"compact_running":false,"disk_size":16552608803}
to an other machine.
I started replication with this:
send: 'POST /_replicate HTTP/1.1\r\nHost:
couchdb1.local.xxx:5984\r\nAccept-Encoding: identity\r\ncontent-length:
90\r\ncontent-type: application/json\r\naccept: application/json\r\nuser-agent:
couchdb-python 0.5dev-r127\r\n\r\n'
send: '{"source": "hulog_events", "target":
"http://couchdb2.local.xxx:5984/hulog_events"}'
reply: ''
connect: (couchdb1.local.hudora.biz, 5984)
send: 'POST /_replicate HTTP/1.1\r\nHost:
couchdb1.local.xxxx:5984\r\nAccept-Encoding: identity\r\ncontent-length:
90\r\ncontent-type: application/json\r\naccept: application/json\r\nuser-agent:
couchdb-python 0.5dev-r127\r\n\r\n'
send: '{"source": "hulog_events", "target":
"http://couchdb2.local.xxxx:5984/hulog_events"}'
(no reply so far)
On the source server (couchdb1) I see following logentries:
Mon, 05 Jan 2009 19:34:21 GMT] [info] [<0.12745.45>] 192.168.0.30 - - 'POST'

I still can access couchdb1 (the source) but every trivial request takes
exactly 5015ms:
balancer:/filespace/couchdb/log# time curl -i http://127.0.0.1:5984/
HTTP/1.1 200 OK
Server: CouchDB/0.9.0a731357-incubating (Erlang OTP/R12B)
Date: Mon, 05 Jan 2009 20:45:46 GMT

Content-Length: 102
Cache-Control: must-revalidate
{"couchdb":"Welcome","version":"0.9.0a731357-incubating","start_time":"Sun, 04

real 0m5.015s
user 0m0.008s
sys 0m0.000s
For these accesses no log entries on couchdb1 are created.
Meanwhile on the destination server (couchdb2) I can see lot of activity:

But the number of documents on the destination servers hasnt been incerasing in
the meantime:
{"db_name":"hulog_events","doc_count":25926,"doc_del_count":10074,"update_seq":36000,"purge_seq":0,"compact_running":false,"disk_size":21927524}
couchdb1 is CouchDB 0.9.0a731357-incubating
couchdb2 is CouchDB 0.9.0a730405-incubating
