OverviewThere is a known issue with memory paging alerts which come up in earlier versions of ExOS 7. If the appliance is using version 7.0.0, 7.0.1 or 7.0.2, it is recommended to upgrade to at least version 7.0.3U1 as the first troubleshooting step. The following fixes are included in this firmware version:
B-04756 - Changed default vm.swappiness sysctl value from default of 60 to 10 to less prefer swapping out memory to disk. This should decrease the number of paging alerts.
D-04400 - Memory leak causes excessive memory usage and paging. A fix for another problem caused a memory leak when there are a large number of tables with lots of partitions.
