We found that with the default vm.swapiness setting of 60, our biggest production WAS app would slowly fill up all of his swap space, run out after 5 days or so, and crash. Setting it to 20 made that problem go away .
I'm pretty unhappy with the way Linux has been managing memory, especially w/rt the block caches being allowed to page out process data. I was hopeful that we could affect some semblance of sane behavior by twiddling vm.swappiness. My experience doing so, however, was that it opened us up to situations where I would start to see processes get pranged by the out- of-memory desperation kill "feature", even though there was quite a bit of memory still sitting unused. It was pretty frustrating. ok bear ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
