Subject Re: High swap usage and network timeouts during heavy publishing

Have you confirmed (via techniques such as the ones described in that the
ActiveMQ process is the one whose pages are getting swapped?

Also, what does top show your buffer usage (i.e. Linux using memory to
buffer disk writes for performance reasons) during this period of time?

Linux has an OS setting (vm.swappiness) that will let you control how
willing the OS is to swap out pages. You could adjust this value to make
paging less likely (or forbid it entirely) if you wanted.
