Hi,
I have a little question about memory usage...
When I do a free, I get:
total used free shared buffers cached
Mem: 18482800 18030668 452132 0 683068 9426792
-/+ buffers/cache: 7920808 10561992
But, when I do a ps, mysql is the only process that takes noticable memory; and it is far from 7.9GBs...
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
mysql 28346 36.0 15.6 3241196 2884692 ? Sl Jul04 981:19 \_ /usr/libexec/mysqld --basedir=/usr --datadir=/IOL/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --skip-external-locking --port=3306 --socket=/IOL/mysql/mysql.sock
Once you removed the buffers and the cached memory from the total used memory... what is left?
Looks like I have "something" (that is not buffers/cached) that takes more than 4GB...
Could it be disk cache or is it included in the cached value?
Any idea?
Thx,
JD
