Thanks Mark. I separated out the processes on different servers, so now ES
has a full server.
I made the changes yesterday and it seems to be stable since then.

Thanks Aaron. Your post was very informative.
Can you recommend any blogposts, articles etc. where I could read more on
this topic?
Thanks again for your help.

Also, we don't recommend running ES alongside other apps. As you can see
contention is an issue and you will have to pay the price there.

You need to read up a bit on how memory is allocated in Linux.
In an ElasticSearch or Database server, this seems to be both, you want
that free column to be 0. All available free memory should be used to
cache files. In your snapshot you have 35GB of file cache listed under the
cached headi
Thanks Uwe. As I mentioned earlier, I did guess that VIRT doesn't indicate
RAM consumption.
What I am concerned about is the 3rd row which shows memory and indicates
that out of the total 50g, 43g is in use. Once this number crosses 45g, my
other databases start behaving badly.
Problem is, even a

Maybe this allows you to figure out what's going on! VIRT means nothing
about consumption, you should look at RES.
Thanks,

Do you know what virtual memory is? You have terabytes of it.

Hi,
I have a single node ES setup (50GB memory, 500GB disk, 4 cores) and I run
the Twitter river on it. I've set the ES_HEAP_SIZE to 5g. However, when I
do "top", the ES process shows the VIRT memory to be around 34g. That would
be I assume the max mapped memory. The %MEM though always hovers
