Out of memory/heap

Just got this out of memory error:

Any ideas? It is running out of heap during http transport?

Why is it that elasticsearch will basically just lock up after an error
like this - isn't there a way to rescue from exceptions and just move on?

Unfortunately you can't really recover from OOM. You really need to restart
the node. The question here is why do you run OOM, the StackTrace is only
the place where it really hit the OOM but likely not where the memory goes.
can you provide more details like your usage pattern ie. if you do faceting
/ sorting etc. and your settings for Xmx etc.

Hi,
Looks like there is a memory leak in one of the following class/method.(stream/buffer memory resource not closed)
Please review if all the streams/buffer memory resources are closed in the following classes/methods.

org.elasticsearch.common.netty.buffer.HeapChannelBuffer.(HeapChannelBuffer.java:42)
org.elasticsearch.common.netty.buffer.BigEndianHeapChannelBuffer. (BigEndianHeapChannelBuffer.java:34)
org.elasticsearch.common.netty.buffer.ChannelBuffers.buffer(ChannelBuffers.java:134)
org.elasticsearch.common.netty.buffer.HeapChannelBufferFactory.getBuffer(HeapChannelBufferFactory.java:69)
org.elasticsearch.common.netty.buffer.CompositeChannelBuffer.copy(CompositeChannelBuffer.java:568)
org.elasticsearch.common.netty.buffer.AbstractChannelBuffer.copy(AbstractChannelBuffer.java:522)
