We are using Hudson to build mixed C++/Java projects with an Ant script. It is running in Tomcat 6, on a Win XP virtual machine.
I have noticed recently that when a user logs off the machine (from a remote desktop session), builds that are currently running tend to suddenly fail without an error message.
Has anyone encountered anything similar or have an idea what might be causing this effect? I can post additional information about our setup if needed, I'm just not sure what's relevant in this case.
EDIT: I have tried running the Tomcat service under various users, but this doesn't seem to help. Tried the standard Local System account, as well as the server Administrator and a domain administrator account.
