> Key: METRON-354
> URL: https://issues.apache.org/jira/browse/METRON-354
> Project: Metron
> Issue Type: Bug
> Affects Versions: 0.2.1BETA
> Environment: Quick dev setup installation using vagrant from HEAD
> Reporter: Anand Subramanian
> Assignee: Jon Zeolla
> Priority: Critical
> Labels: metronqe
> Attachments: messages, messages-20160725, output-platform-info.rtf

> This is a single node quick-dev deployment from HEAD using vagrant on a Macbook Pro. The platform-info output is attached.
> After startup, I noticed multiple java process OOM’s due to lack of swap space. Here’s one pasted below for reference and the full /var/log/messages files are attached (see messages-20160725 for the OOM errors).
> I did not observe the OOM with earlier with single node vagrant deployments. Note that I have not added additional topologies.
> Is this possibly due to the new changes that was introduced related to separating out indexing? Please let us know. Also, I was considering increasing the # of CPUs and RAM on the vagrant and re-try the single node setup. Please advice if it is good to try that route.
