Hi people. I'm using tomcat5 to host a commercial web site, and due to some integration issues we are using a single service with two CoyoteConnectors - one on port 8080 and one on port 8081. Here is the relevant configuration:
<Service name="Catalina"> <Connector port="8080" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" redirectPort="8443" acceptCount="100" debug="0" connectionTimeout="20000" disableUploadTimeout="true" /> <Connector port="8081" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" redirectPort="8443" acceptCount="100" debug="0" connectionTimeout="20000" disableUploadTimeout="true" /> I've noticed that some times, when catalina is starting, I get this error in the logs: Nov 24, 2005 4:28:30 PM org.apache.coyote.tomcat5.MapperListener init WARNING: Error registering contexts java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextEntry(HashMap.java:782) at java.util.HashMap$EntryIterator.next(HashMap.java:824) at java.util.HashMap.putAllForCreate(HashMap.java:424) at java.util.HashMap.clone(HashMap.java:656) at mx4j.server.DefaultMBeanRepository.clone(DefaultMBeanRepository.java:56) at mx4j.server.MBeanServerImpl.findMBeansByPattern(MBeanServerImpl.java:1603) at mx4j.server.MBeanServerImpl.queryObjectNames(MBeanServerImpl.java:1568) at mx4j.server.MBeanServerImpl.queryMBeans(MBeanServerImpl.java:1512) at org.apache.coyote.tomcat5.MapperListener.init(MapperListener.java:115) at org.apache.coyote.tomcat5.CoyoteConnector.start(CoyoteConnector.java:1537) at org.apache.catalina.core.StandardService.start(StandardService.java:489) When that happens, HTTP requests to the second connector (port 8081) return with error 400 - no host matches, while requests to the first connector are handled just fine. It looks to me like a race condition where something (possibly MBeanServerImpl) isn't locking a shared resource (or isn't locking it properly) and an contained HashMap gets modifier concurrently. I though initially about writing to the dev list, but I don't have any idea what is that mx4j so I'm not sure if its the correct place to ask. BTW - I'm using tomcat 5.0.28.
