Hi all,
We've been using "free" command to collect memory info thorugh scripts.
Recently some of our
machines having RHEL Update 2 were upgraded to RHEL Update 6. After the
upgrade,
the memory info returned by the "free" command is lower than what it used to
report
in RHEL U2. The difference is in the order of 100 MB.
For eg. On one of our machine which has 16GB, the "free -m" command used to
report 15893 MB of RAM
when the machine used to have RHEL Update2. Now when the machine has been
upgraded
to RHEL Update6, the "free -m" command reports the memory as 15709 MB.
This difference in memory does not do much harm except that it defeats the
purpose of some
scripts used in monitoring.
Does anyone know why this happens, how this can be rectified.
Regards
Anoop
