I mounted the apache directory /var/www/html on a GFS volume (with the noatime option, but I can remove it, as the nodes synchronize with NTP).</P> <P> </P> <P>My problem is that:<BR>I'm alone on my test machine (but other nodes are used), and, when I go from a PHP file to another with my browser, I've to wait for 30 seconds !!! On the server, the top command shows that dlm_sendd process uses 95% of the CPU (and apache about 1%). Anf of course, the load average grows - from 0 to 10 -.</P> <P> </P> <P>Thank's for your help</P> <P>Jerome</P></br><p style="margin-top:11px;padding-top:3px;background-image: url(http://mail.lycos.co.uk/Images/Mail/_content/dot.gif);background-repeat: repeat-x;background-position: 0px 0px;"></a> <strong>Lycos iQ</strong> : Gagnez des places pour la Coupe du Monde en Allemagne.
