Just something odd I noticed while reviewing the SGE job success emails
for MIMEStatBot: When the script runs on a Solaris host, the "Max vmem"
value is consistently between 20 and 25 M, but on Linux it jumps up to
over 160 M.
Furthermore, the same effect can be reproduced with a much simpler test
script. Compare:
vyznev@willow:~$ perl -e 'system "uname -a; ps -o comm,vsz -p $$"'
SunOS willow 5.10 Generic_147441-19 i86pc i386 i86pc Solaris
COMMAND VSZ
perl 6632
vyznev@nightshade:~$ perl -e 'system "uname -a; ps -o comm,vsz -p $$"'
Linux nightshade 2.6.32-5-amd64 #1 SMP Sun May 6 04:00:17 UTC 2012
x86_64 GNU/Linux
COMMAND VSZ
perl 104364
What's going on here? It it just an accounting difference, or does a
Perl process on Linux really consume over 100 megabytes more memory than
on Solaris?
