Some data showed by top command looks like completly trashed.
Fragment from top output:
Mem: 2075784k total, 2053352k used, 22432k free, 19260k buffers
Swap: 2096472k total, 136k used, 2096336k free, 1335080k cached
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ SWAP nFLT WCHAN COMMAND
14515 mysql 20 0 1837m 563m 4132 S 39 27.8 27:14.20 1.2g 18 - mysqld
How it is possible that swap ussage is 136k and swapped out portion of (in
this case) mysqld process is 1.2g ?
Mayby some other data from /proc/<pid> shows some *real* data ?
Above is on procps 3.2.7 and kernel 2.6.22.12.
