centOS memory leak - MEGABYTES per day

hi
i've notice a huge problem on my newly installed centOS server and i have no idea how to solve it and where to start..
memory on server 3 GB and it goes down, down, down..
after reboot it shows 71mb used
after a hour its 76mb
and after 24h it's around 200
later = more

i have NO idea where goes this mem..
i've checked ps -AF (no info in SZ column about where so much memory is hiding)
i did shutdown all services (atm there only: crond, haldaemon, messagebus, network, rawdevices, sshd, syslog and some dm-raid45 which i have no idea how to shut down (i have no raid but it just loading on startup even blacklisted in /etc/modprobe.d/blacklist))
still! system loosing memory in nowhere

wtf & what to do?

Linux 2.6.18-194.32.1.el5 #1 SMP Wed Jan 5 17:53:09 EST 2011 i686 i686 i386 GNU/Linux

Need to create a memory leak

Hi. This might be a strange request, but does anyone have any idea on a simple shell script that would use more and more memory as it ran? Like a purposeful leak. I want to test the behaviour of an already running program when the machine runs out of memory. Thanks! (4 Replies)

NAME
pminst - find modules whose names match this pattern SYNOPSIS
pminst [-s] [-l] [pattern] DESCRIPTION
Without argumnets, show the names of all installed modules. Given a pattern, show all module names that match it. The -l flag will show the full pathname. The -s flag will separate the base directory from @INC from the module portion itself. EXAMPLES
$ pminst (lists all installed modules) $ pminst Carp CGI::Carp Carp $ pminst ^IO:: IO::Socket::INET IO::Socket::UNIX IO::Select IO::Socket IO::Poll IO::Handle IO::Pipe IO::Seekable IO::Dir IO::File $ pminst '(?i)io' IO::Socket::INET IO::Socket::UNIX IO::Select IO::Socket IO::Poll IO::Handle IO::Pipe IO::Seekable IO::Dir IO::File IO Pod::Functions The -s flag provides output with the directory separated by a space: $ pminst -s | sort +1 (lists all modules, sorted by name, but with where they came from) $ oldperl -S pminst -s IO /usr/lib/perl5/i386-linux/5.00404 IO::File /usr/lib/perl5/i386-linux/5.00404 IO::Handle /usr/lib/perl5/i386-linux/5.00404 IO::Pipe /usr/lib/perl5/i386-linux/5.00404 IO::Seekable /usr/lib/perl5/i386-linux/5.00404 IO::Select /usr/lib/perl5/i386-linux/5.00404 IO::Socket /usr/lib/perl5/i386-linux/5.00404 IO /usr/lib/perl5/site_perl LWP::IO /usr/lib/perl5/site_perl LWP::TkIO /usr/lib/perl5/site_perl Tk::HTML::IO /usr/lib/perl5/site_perl Tk::IO /usr/lib/perl5/site_perl IO::Stringy /usr/lib/perl5/site_perl IO::Wrap /usr/lib/perl5/site_perl IO::ScalarArray /usr/lib/perl5/site_perl IO::Scalar /usr/lib/perl5/site_perl IO::Lines /usr/lib/perl5/site_perl IO::WrapTie /usr/lib/perl5/site_perl IO::AtomicFile The -l flag gives full paths: $ filsperl -S pminst -l Thread /usr/local/filsperl/lib/5.00554/i686-linux-thread/Thread/Queue.pm /usr/local/filsperl/lib/5.00554/i686-linux-thread/Thread/Semaphore.pm /usr/local/filsperl/lib/5.00554/i686-linux-thread/Thread/Signal.pm /usr/local/filsperl/lib/5.00554/i686-linux-thread/Thread/Specific.pm /usr/local/filsperl/lib/5.00554/i686-linux-thread/Thread.pm AUTHORS and COPYRIGHTS Copyright (C) 1999 Tom Christiansen.
