I'm having a VM issue on one of my servers running 2.4.20.
The box reports the following:
adam@foxy:~$ cat /proc/meminfo total: used: free: shared: buffers: cached: Mem: 4041986048 3968524288 73461760 0 619249664 1551077376 Swap: 2001215488 171663360 1829552128 MemTotal: 3947252 kB MemFree: 71740 kB MemShared: 0 kB Buffers: 604736 kB Cached: 1494600 kB SwapCached: 20124 kB Active: 1632528 kB Inactive: 2006628 kB HighTotal: 3080176 kB HighFree: 67324 kB LowTotal: 867076 kB LowFree: 4416 kB SwapTotal: 1954312 kB SwapFree: 1786672 kB
As you can see there is plenty of memory sitting in buffers/cache. The problem is that when our daily cronjobs run, the box starts swapping and the load goes up to 30. The cronjobs are just the normal system cronjobs like updatedb, checksecurity, etc.
I had this problem a while ago with 2.4.6-xfs and 2.4.14-xfs, but this is stock 2.4.20 and I was under the impression that the VM was relatively OK by now.
adam@foxy:~$ grep -i mem /boot/config-2.4.20 # CONFIG_NOHIGHMEM is not set # CONFIG_HIGHMEM4G is not set CONFIG_HIGHMEM64G=y CONFIG_HIGHMEM=y # Memory Technology Devices (MTD) # CONFIG_BLK_DEV_UMEM is not set # CONFIG_DEBUG_HIGHMEM is not set
Any suggestions?
Thanks,
