Of late I'm seeing the following exception quite often:

Me too. Cleaning the workspace helps but the error comes back after the first clean build, e.g.: https://hudson.eclipse.org/hudson/job/mylyn-reviews-nightly/121/

I noticed that this has only happened with hudson-slave2. hudson-slave1 goes smooth. Possible version incompatibility/old binary running on that machine ?

Comment 3 Matthias Sohn

The egit build hits a similar problem on slave1 [1]

Yes, it is a Hudson bug, but there doesn't appear to be a fix yet.


That looks a lot like this:

http://issues.hudson-ci.org/browse/HUDSON-6604

As per bug 339027, stopping all the jobs to get a "clean" restart is essential.
