VOMS server fails with high number of VOs

VOMS server of gLite 3.2 is more memory greedy, it starts failing when configured to serve more than 10 (approx.) VOs.

Change -XX:MaxPermSize parameter of CATALINA_OPTS to the value of at least 512m in /etc/tomcat5/tomcat5.conf

 CATALINA_OPTS="-Xmx1508M -server -Dsun.net.client.defaultReadTimeout=240000 -XX:MaxPermSize=512m"

and add

 * soft nofile 2048
 * hard nofile 2048

into /etc/security/limits.conf.
