[rt-users] RT 4.0.2 too much CPU hungry !

[Michele Pinassi]

Hi all,

i've installed RT 4.0.2 in my office over a Debian. Here's apache2 SSL
config:

<IfModule mod_ssl.c>
<VirtualHost _default_:443>
    ServerAdmin webmaster@localhost

        AddDefaultCharset UTF-8

        DocumentRoot "/opt/rt4/share/html"
        <Location />
            Order allow,deny
            Allow from all
        </Location>

    SetHandler modperl
        PerlResponseHandler Plack::Handler::Apache2
        PerlSetVar psgi_app /opt/rt4/sbin/rt-server

    PerlSetVar MasonStaticSource true
    PerlSetVar MasonBufferPreallocateSize 2048000
    PerlSetVar MasonDataCacheDefaults "cache_class=> MemoryCache,
cache_depth => 4"
    PerlSetVar MasonPreloads '/Elements/*'

        <Perl>
            use Plack::Handler::Apache2;
            Plack::Handler::Apache2->preload("/opt/rt4/sbin/rt-server");
        </Perl>

    <Directory />
        Options FollowSymLinks
        AllowOverride None
    </Directory>

    <Directory /opt/rt4/share/html>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride None
        Order allow,deny
        allow from all
    </Directory>

and this is RT_SiteConfig.pm:

root@centralino:/opt/rt4/etc# cat RT_SiteConfig.pm

...

Set($WebPort, 443);

Set( @Plugins, qw(RT::Extension::JSGantt RTx::Calendar) );
Set( @Plugins, qw(RT::Authen::ExternalAuth) );

...

We use LDAP for external auth and all RT works under SSL for security
reason.

The problem is that our apache2 istance use almost 100% of CPU and over
1GByte of RAM (plus some swap...):

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND   
 6984 www-data  20   0 87936  62m 4016 R 99.4  6.1   0:07.03
apache2                                                                         
              

 7012 root      20   0  2436 1136  896 R  0.7  0.1   0:00.14 top     

and web is very slow responsiveness...

Any hint ?

Michele
