Description of problem:

I have to restart my tomcat5 server several times to avoid the following:

4-Mar-08 12:56:12 AM org.apache.catalina.connector.MapperListener init
WARNING: Error registering contexts
java.util.ConcurrentModificationException

4-Mar-08 12:56:12 AM org.apache.jk.common.ChannelSocket init

When I get it, the webapps do not load properly.


Version-Release number of selected component (if applicable):

I installed Tomcat 5.5.26 on Fedora 8 x86_64 with RPMs:

108$rpm -qa | grep tomcat
jakarta-commons-pool-tomcat5-1.3-9jpp.3.fc8
tomcat5-servlet-2.4-api-5.5.26-1jpp.2.fc8
tomcat5-jsp-2.0-api-5.5.26-1jpp.2.fc8
tomcat5-jasper-5.5.26-1jpp.2.fc8
jakarta-commons-collections-tomcat5-3.1-9jpp.2.fc7.1
tomcat5-common-lib-5.5.26-1jpp.2.fc8
tomcat5-server-lib-5.5.26-1jpp.2.fc8
tomcat5-admin-webapps-5.5.26-1jpp.2.fc8

jakarta-commons-dbcp-tomcat5-1.2.1-10jpp.2.fc8
tomcat5-5.5.26-1jpp.2.fc8

Additional info:

The machine is dual CPU with dual cores, and is using gcj as installed by
default with Fedora 8 RPMs:

145$rpm -qa | grep gcj
java-1.5.0-gcj-devel-1.5.0.0-17.fc8
libgcj-4.1.2-33
libgcj-devel-4.1.2-33

libgcj-src-4.1.2-33
