I'm using hudson 1.297.

My build job output BUILD SUCCESSFUL and got stuck:

...
rm -f release_build_analyzer/ba-doc-4.5.0.tar.gz
cd release_build_analyzer && tar zcf ba-doc-4.5.0.tar.gz ./*
BUILD SUCCESSFUL
BUILD SUCCESSFUL

It's a build through make.

I noticed the following error in the log for the build machine that started
about 1ish pm and repeated numerous times:

According to
http://hudson.gotdns.com/wiki/display/JENKINS/Spawning+processes+from+build,
hudson should just print out a warning and move on. It did not. The job stayed
hung for hours.
