Subject [jira] [Commented] (COUCHDB-1856) hang and restart when replicate remotely of database that has doc > 10M, with 600kb/s network speed

    [ https://issues.apache.org/jira/browse/COUCHDB-1856?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13825133#comment-13825133

Ed Levin commented on COUCHDB-1856:
-----------------------------------

Having a very similar issue but on Ubuntu 12.04, strangely enough, while attempting to replicate
Node.js public NPM registry.

When replication starts, beam process (Erlang) starts consuming memory and within a few min
takes up all of 1.5gb available system ram as well as 1gb swap, after which time the process
crashes with code 137 (OOM) and replication restarts (continuous turned on).

I documented my case with detail on user mailing list:

> When I remotely replicate a database that has doc > 10M, with 600kb/s network speed,
in a win7 64bit platform with couchdb 1.3.1, the couchdb server will launch the replication,
but erl.exe soon reach up to commiting > 2GB memory, then
> couchdb server hangs until a restart.
> Two things that might helpful:
> 1) It's fine for me to replicate the database in the same couchdb server (in the same
machine);  
> 2) My web browers, IE9/10, chrome, firefox, also hang or without response, at sometimes,
 when I open the documents in the database with URL;
