Subject [jira] Commented: (COUCHDB-993) Replication is crashing when changes feed was consumed
Date Wed, 29 Dec 2010 16:13:47 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-993?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12975817#action_12975817

Sebastian Cohnen commented on COUCHDB-993:
------------------------------------------

I cannot reproduce this error locally anymore. However I still see some odd peaks in resource
usage (memory/cpu). For now it looks okay, but I already said to Paul on IRC couple of days
ago that I'm going to perform some more extensive testing and profiling to figure out where
and - maybe with your help - why these occur. I'm not sure if these usage patterns are expected
or not, but I hope that there is some more room for improvement here.

> Yesterday I hit a bug, where pull replication is dying which is resulting in a {exit,{json_encode,{bad_term,<0.133.0>}}}
error (CouchDB is trying to encode a PID into JSON).
> Adam and Paul had a look at this issue yesterday and they found the underlying issue:
There was a missing clause catching the exit message when the changes feed was consumed and
ibrowse closes the HTTP connection for that feed.
> Adam wrote a quick patch yesterday, which I'll append here too (applies cleanly to 1.0.x
at time of writing).
> (Sorry for any inaccuracy, I only understood the issue partially)
