Hi,
I am using mod_perl 1.99_13, with Apache 2.0.49. When I start the
processes, free shows me that about 17 MB of swap is used. And ps -aux,
shows me that each httpd process eats up to 1.1 %MEM. But after about 30
minutes running, the swap memory usage will increase to up to about 200
MB, and each httpd process eats up to 2.5 %MEM. Sometimes the swap usage
will just go to 100%, and I have to restart httpd to make it returns to
normal. My RAM is 1 GB with 2 GB swap, and almost all of the scripts are
run inside ModPerl::Registry.
Is there any memory leakage? What can I do to check it?
My httpd.conf looks like this:
<IfModule prefork.c>
StartServers 20
MinSpareServers 30
MaxSpareServers 50
MaxClients 50
MaxRequestsPerChild 6000
</IfModule>
And my startup.pl:
use Apache2 ();
use ModPerl::Registry ();
use lib "/var/www/lib";
use Apache::DBI ();
use DBI ();
use HTML::Template;
use File::Find;
print STDERR "Pre-loading HTML Templates...\n";
find(
sub {
return unless /\.tmpl$/;
HTML::Template->new(
filename => "$File::Find::dir/$_",
cache => 1,
);
},
'/var/www/tmpl'
);
