bitbake package-index for opkg relies on flock() and this does not behave properly when the lock file is on an NFS share; thus we have to do some copying around to avoid this from being a problem, however this takes much longer. Ideally all of the builders would be able to safely poke into the shared location and then the package index could be assembled at the end.
Fixed in Production. Commit pending to yocto-autobuilder master
waiting for review in order to pull into master
