Then I installed mysql55-server from ports and rebooted the system. If I try to make dump with running mysql-server, system freezes and mksnap_ffs uses 100% of cpu. If I disable journaling (tunefs -j disable /), mksnap_ffs / /.snap/snapshot works OK. If I stop mysql-server, mksnap_ffs / /.snap/snapshot works OK. The same problem with apache. The problem like bin/167156, but more extensive. >How-To-Repeat: Instlall freebsd 9.0 amd64, update to p4, install mysql55-server from ports, start mysql and make mksnap_ffs / /.snap/snapshot [db:/etc/mail]#mount /dev/aacd0p3 on / (ufs, local, journaled soft-updates) devfs on /dev (devfs, local, multilabel) /dev/aacd0p4 on /var/log (ufs, local, journaled soft-updates) [db:/etc/mail]#pkg_info cmake-2.8.9 A cross-platform Makefile generator cmake-modules-2.8.9 Modules and Templates for CMake mysql-client-5.5.27 Multithreaded SQL database (client) mysql-server-5.5.27 Multithreaded SQL database (server) [db:/etc/mail]# >Fix: >Release-Note: >Audit-Trail: >Unformatted:
