"free" shows that most almost all memory is "in use" : total used free shared buffers cached Mem: 513596 508664 4932 0 908 8360 -/+ buffers/cache: 499396 14200 Swap: 1953768 74364 1879404 but "ps uax" shows that only very less memory is "RSS", most processes are completely swapped out (which matches the sound of the hard disks on my raid5!) summing up all RSS fields in "ps aux" output gives only 31276, summing up VSZ shows 578396. reboot did not help, nor does switching of Xserver, (idle) apache etc. full output of ps and dmesg available on request. now I'm back with the kernel-pae which works fine! free shows total used free shared buffers cached Mem: 505788 499572 6216 0 3852 357880 -/+ buffers/cache: 137840 367948 Swap: 1953768 196 1953572 sum of RSS in "ps aux" is 185508, sum of VSZ is 633208. for kernel-pae the ps numbers match the output of free and the overall system behaviour, for kernel-default the ps output seems bogus (or the memory hog is not related to processes ?!) what's wrong with kernel-default ? did anyone ever test -default, now that -pae seems to be the default 32 bit kernel ? where does all the memory go, or what's the problem with ps output ? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
