I looked at the error and the jenkins jobs a bit more and I think the real problem is that the FreeBSD_Head job is being run in parallel with the Build-UFS-image job, because the FreeBSD_Head job completes without issue and the Build-UFS-image job is not being run with -j <anything>. I know based on past experience if the tree is updated but not rebuilt with -DNO_CLEAN and installkernel/installworld is being run, sporadic build failures like this will occur, depending on whether or not something needs to be [re]built.

One way to deal with this issue is to svn up a source tree, then rsync the checked out copy of the source tree to a unique memory disk, build from there, and install to a unique location as well. Using the jenkins job identifier should be enough… but I’m not sure what the best way with Jenkins is to do this, partly because I don’t know what plugins are installed on the Jenkins server.

Thanks!
