Hi, I have ES 1.7, and I got an "Out of Memory Error, Java Heap Space" I know the cause is that I don't have enough RAM for the amount of data I'm inserting ES. Unfortunately, new hardware is coming only in a few weeks. My questions are: 1. How to recover the index (it's status is yellow) so that I could keep using it? 2. How to insert small amounts of data so it won't happen again? (I'm using logstash 2.1 and filebeat, and have limited the bulk\_max\_size to 20) Thanks ---

You can remove the replica and then readd it via the APIs. > [@muhamadli302](#): > > 1. How to insert small amounts of data so it won't happen again?

Hi, thanks for the answer 1. But I still have a problem... When looking at the index on kibana it gives me the OOM error and I can't query the index. 2. I assume it's the problem since it happens when I'm inserting large amounts of data. For example I first had bulk\_max\_size defined to 50 (it's the default) and I got OOM after an hour or so... When changing to bulk\_max\_size to 20 it worked for almost a week, inserting 130 million documents. ---

On kibana I see: "ElasticsearchException[java.lang.OutOfMemoryError: Java heap space]" I can't get you the ES logs right now since it on a closed network. ---
