Daniel When I switch from master to DM-630 using the recipe I just described in separate email, when I am bringing services up I see: qserv-start.sh Starting MySQL. [ OK ] Starting xrootd./usr/local/home/becla/stack/Linux64/qserv/tickets.DM-630-gb26efd78da/etc/init.d/qserv-functions: line 37: 18969 Segmentation fault (core dumped) /usr/local/home/becla/stack/Linux64/xrootd/master-gfc9bfb2059/bin/xrootd -c /usr/local/home/becla/stack/Linux64/qserv/tickets.DM-630-gb26efd78da/etc/lsp.cf -l /usr/local/home/becla/stack/Linux64/qserv/tickets.DM-630-gb26efd78da/var/log/xrootd.log -n worker : Manager of pid-file quit without updating file.

STARTED Starting mysql-proxy. [ OK ] Starting qserv-czar [ OK ] The same happens when I run ./Linux64/qserv/tickets.DM-630-gb26efd78da/etc/init.d/xrootd start Any ideas what could possibly go wrong? If I switch back to master branch, things work fine. If I make a trivial change in the master and switch to the "master-ga7082f1e02-dirty" using the recipe I described, things work. So, it makes me think the problem really is with DM-630. P.S. I tried to reproduce it by hand, but it is not obvious to me how (and it is getting late :) Any thoughts?
