[jira] [Resolved] (COUCHDB-1757) CouchDB 1.3.0rc3 crashes when
_replicator contains a lot of docs
[ https://issues.apache.org/jira/browse/COUCHDB-1757?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sander Dijkhuis resolved COUCHDB-1757.
--------------------------------------
Resolution: Not A Problem
> CouchDB 1.3.0rc3 crashes when _replicator contains a lot of docs
> ----------------------------------------------------------------
>
> Key: COUCHDB-1757
> URL: https://issues.apache.org/jira/browse/COUCHDB-1757
> Project: CouchDB
> Issue Type: Bug
> Components: Database Core
> Reporter: Sander Dijkhuis
>
> I’m deploying an experimental game based on CouchDB with one user per database. For access control, I’m using several _replicator docs per user:
> - one filtered replication from the shared db to the user db,
> - one unfiltered replication from the user db to the shared db,
> - two replications using doc_ids per ‘friendship’ (to share both profiles).
> At the moment, this results in 420 continuous replications running. CouchDB 1.3.0rc3 on Ubuntu crashes a couple of seconds after starting, and doesn’t crash when I temporarily remove the _replicator database. When I used 1.3.0rc1, CouchDB would crash after a few minutes to a few hours.
> Some details from the crash report are below, filtered for privacy, to avoid repetition and to hide the _design doc that’s shown in the log. Let me know if you need more detail or if I should share one of the _design functions used.
> Am I abusing the replication system, or can I change a setting to allow for longer timeouts?
> --
> First, I get something like this for each _replicator doc:
