Thanks for your reply. No, I have not journaling activated, are filesystems with soft updates, but no journal. I am watching the syslog, and after a crash (4 weeks ago) I see that a filesystem was not fully cleaned at startup: <filesystem>: UNEXPECTED SOFT UPDATE INCONSISTENCY; RUN fsck MANUALLY. The system stopped, and a single user shell opened. But the system administrator at this moment simply ignored that issue, and hit "exit" in the shell. I believe that error was the start of my headaches: never an unclean filesystem must be mounted. Regards
