Agreed. I understand swap space should be allocated to the ML process as a contingency, as Linux will kill the process if it runs out of memory. It provides time for administrators to figure out what is going on, before there is a failure.

If ML starts swapping at all it will run dog slow, so if it were me I'd just keep an eye on the swap space and see if you even need to add more, most likely your 64GB of swap partition is hardly touched. ----------------------------------------------------------------------------- David Lee Lead Engineer MarkLogic Corporation [email protected] Phone: +1 650-287-2531 Cell: +1 812-630-7622 www.marklogic.com This e-mail and any accompanying attachments are confidential.
