---------------------------------------
Hello Folks,
Is there anything I can provide you on this issue to expedite the resolution of
this issue in the next early releases?
> CouchDB Memory Leak - Beam.smp
> ------------------------------
>
> Key: COUCHDB-2058
> URL: https://issues.apache.org/jira/browse/COUCHDB-2058
> Project: CouchDB
> Issue Type: Bug
> Security Level: public(Regular issues)
> Components: Database Core
> Reporter: Rohit Sharma

> Hello,
> I am experiencing performance issue with CouchDB.
> Use Case: I am working on a process that retrieves the data from RDBMS and
> process them into JSON document and POST them to the CouchDB.
> I am trying to POST around half a million documents, most of them in batches
> (_bulk_doc) of 10,000 and have tried with batch of 5,000, 15,000, and 20,000.
> Whole process takes around 90-100 minutes.
> During the life of the process, Memory Consumption by CouchDB keeps on
> growing and memory is not released when CouchDB has finished working.
> So if the memory consumption by CouchDB was 60% at the time process finishes,
> memory consumption will remain 60% and not reducing.
> Subsequently, when the process starts running again. memory consumption is
> Maxed out and CouchDB restarts itself. This restart fails the process that I
> am running. Looking at the Syslogs , I see Out Of Memory Error by the CouchDB
> process and killing statement.
> The CouchDb process that has the issue is the "beam.smp" of Erlang.
> At this point, I have tried upgrading the memory of the server to see if this
> resolves the issue, unfortunately, the issue persists. Memory Leak is there
> and Usage keeps on growing until CouchDB restarts/crashed.
> I also have tried running garbage collection from Erlang command
> (erlang:garbage_collect().) line but it didn't do anything.
> At this point, I am out of ideas and not sure what is going on here. Any
> input/suggestion is highly appreciated!
> Env:
> Platform: Linux (Red Hat release 6.4 (Santiago))
> CouchDB: 1.3 and have tried with 1.5 as well
> RAM: Tried with 2G, 4G, and 8G
> CPU: 2 cores
> Process:/usr/lib64/erlang/erts-5.8.5/bin/beam.smp -Bd -K true -A 4 -- -root
> /usr/lib64/erlang
