ESM Appliance using ALL RAM

Jump to solution

So I have an ESM box with 32 GB of RAM; we have had performance issues so I bumped it up to 64GB today and within 20 minutes all 64GB were being used. I added 32, now we have 96, and in less than an hour, I have the below:

Any ideas?

Linux simply manages memory this way - if you add another 32G, it will use that too.

To get a more true measurement of memory usage, use the "free" command.  The "-/+ buffers/cache" line shows you the adjusted memory values after the I/O cache is accounted for.

I killed the JAVA and MYSQLD processes that were at the top, but it's slowly creeping back up
