Subject Apache2::SizeLimit and x64_86
Date Mon, 11 Apr 2011 01:24:50 GMT
Hi all,

On x86_64 I noticed that perl .so files (XS modules) appear to use a
lot more memory than they do on 32-bit architectures.

In particular, /proc/$$/smaps reports a ~ 2MB segment associated with
the .so library that is not reported in the 32-bit case.
For more details, see my posting to the Centos mailing list:
http://lists.centos.org/pipermail/centos/2011-April/109530.html

My questions are:

- Does this represent real (physical) memory usage?

- Apache2::SizeLimit seems to be including these segments in its size
calculation. Is there a way to have Apache2::SizeLimit ignore them?

Thanks,
ER
