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?

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)

pminst
PMINST(1p) User Contributed Perl Documentation PMINST(1p)
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::Lines
/usr/lib/perl5/site_perl IO::WrapTie
/usr/lib/perl5/site_perl IO::AtomicFile
The -l flag gives full paths:
