I noticed it several times since the new profile was activated about two weeks ago - the build with selenium profile on hudson slave hangs too often and the only way to stop it is to terminate it forcibly (see http://hudson.magnolia-cms.com/job/magnolia-bundle_trunk-with-selenium_profile). It does not get stuck always at the same point, even though most often this seems to happen when starting firefox to run the selenium based integration tests.
