Hi Jacek, The socket parameter should be in qserv-run-dir (i.e. /home/qserv/qserv-run/git below), not in /var/lib/mysql/mysql.sock as printed in your log. xrootd deduce this value from this env variable: QSW_DBSOCK (=/home/qserv/qserv-run/git/var/lib/mysql/mysql.sock) This env variable is set in ~/qserv-run/git/etc/sysconfig/qserv (see MYSQLD_SOCK) this file is read by ~/qserv-run/git/etc/init.d/xrootd maybe you can print/debug value of QSW_DBSOCK in ~/qserv-run/git/etc/init.d/xrootd above to see what happen.
