When virtuoso starts it attempts to get an exclusive lock on the .db file to make absolutely sure it is the only process using this file. If it fails to get this lock, this normally means the pid of the process that holds the lock is printed. In your case however it appears to be unable to ask for a lock since your filesystem type does not support it. I will fix the code to make sure we report this condition in a more understandable way. Since your earlier emails indicated it was working on the same location before your reboot, it could be that the system failed to restart an appropriate lock manager for your fs, for instance when you use NFS, the nfslock daemon should be running. Can you tell me what filesystem type you are using for the filesystem that contains: /projects/rdesc/virtuoso-opensource/var/lib/virtuoso/db/virtuoso.db Patrick
