Description Alex Panchenko

Could you please restart the hudson, as it doesn't build some projects for a few days.
It happened after "Hudson using only 2 executor threads	?" discussion, see
http://dev.eclipse.org/mhonarc/lists/cross-project-issues-dev/msg07164.html

The error message could be seen e.g. at
https://hudson.eclipse.org/hudson/job/dltk-nightly/scmPollLog/?
