Subject [jira] Updated: (COUCHDB-597) Replication tasks crash.
Date Sun, 20 Dec 2009 03:08:18 GMT

     [ https://issues.apache.org/jira/browse/COUCHDB-597?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Adam Kocoloski updated COUCHDB-597:
-----------------------------------


Also, I don't really understand why the "after" clause is necessary in that paste.  I tried
adding a connect_timeout to ibrowse but didn't get any conn_failed messages.  It really does
seem like a connection is made but then the request just stalls.  I suppose it's possible
that a connection took 9 seconds (e.g. 3 consecutive TCP retransmits), and then CouchDB took
more than 1 second to respond with the headers.  Seems unlikely, though.  It makes me think
we need to add this "after' clause to couch_rep_httpc too.

> If I kick off 10 replication tasks in quick succession, occasionally one or two of the
replication tasks will die and not be resumed. It seems that the stat tracking is a little
buggy, and under stress can eventually cause a permanent failure of the supervised replication
task;
