I am currently running 2 instances of continuum as windows services on a single Windows 2003 server (running as a VMware virtual machine). The first instance was installed about 6 months ago and has run pretty well. I just installed a second instance and have noticed a problem with its performance and availability. When a build is running on the first instance, this generally causes the second instance to become unresponsive almost every time (i.e. I get a 404 not found message when I try to access it in my browser). The service will eventually come back on its own after a few minutes but If I look in the wrapper.log I see messages like the following ERROR | wrapper | 2007/08/09 09:27:50 | JVM appears hung: Timed out waiting for signal from JVM. ERROR | wrapper | 2007/08/09 09:27:50 | JVM did not exit on request, terminated STATUS | wrapper | 2007/08/09 09:27:55 | Launching a JVM... INFO | jvm 5 | 2007/08/09 09:27:57 | Wrapper (Version 3.1.2) http://wrapper.tanukisoftware.org
Another issue that has been occurring on the second server is that builds often run indefinitely. It's almost as if the build process has died somehow but continuum never noticed so the clock just keeps ticking. I am able to clean these builds up directly in the database but I can't figure out why it keeps happening. A little background about the environment. I have set up all projects in both continuum instances as shell projects but the builds themselves use Maven 2. We were unable to get the Maven 2.0 project type to work correctly and the shell project type worked so we went with it. The maven build is executing some python scripts which are used to process and transform XML documentation using XSLT (a little convoluted I know but I inherited it). The transformation is done using the Java Saxon library which tends to require a lot of memory and CPU. I have a strong hunch that both of my issues are somehow interrelated but am not sure where to start. Java 1.5.0_10 Maven 2.0.4 Python 2.4.1 Saxon 6.5.5 Windows 2003 server running as a VMWare virtual machine on Intel Xeon 3GHz CPU w/ 3.75G RAM Any help or suggestions are greatly appreciated, Eric
