I have server with 32Gb RAM under Windows Server 2012 R2 Standard.  
I have installed on server:

1. ES 1.6.0 - takes 8Gb of RAM, configured as single node.  
ES configuration:

> cluster.name: xxxxx  
> bootstrap.mlockall: true  
> network.host: xxxxx  
> transport.tcp.port: xxxxx  
> http.port: xxxxx  
> index.search.slowlog.threshold.query.warn: 10s  
> index.search.slowlog.threshold.fetch.warn: 1s  
> index.indexing.slowlog.threshold.index.warn: 10s  
> monitor.jvm.gc.young.warn: 1000ms  
> monitor.jvm.gc.old.warn: 10s  
> script.inline: on  
> script.indexed: on

1. MS SQL Server 2008R2 - takes 16Gb of RAM.  
When I just started ES - all is fine, works without any timeouts.  
But after 3-4 days I'm starting get timeouts during different ES operations (search, msearch, bulk insert).  
During getting timeouts BigDesk shows that do not exist any problems with HeapMemory (~5-6 Gb out of 8Gb is used), CPU (cpu usage ~30-40%), Search requests per second ( 50-80 requests per second).  
I turned on slow logging and noticed that number of records in elasticsearch\_index\_search\_slowlog.\* files usually grows day by day and some queries are executed in 1-2 minutes.  
The volume of indexed documents is the same in 3-4 days approximately, so I do not think that it could be a reason.  
If I restart ES - it helps, but situation is repeated in 3-4 days.  
Any hints what could it be?  
On what should I pay attention in order to recognize possible problems?

About 2 millions of documents, it takes about 10Gb on hard disk.
