Hi Kirk, I am not sure how can you use flock (which is a system call if I remember right), but fuser definitely tells you what process locks the file. Please make sure that you are using the "fuser" command and not something else. If this does not work, you can kill processes one by one until you will find the culprit. Also you can try to unmount the partition if mount lets you do so, or you can even make a back-up copy of your mailbox file, an then remove the old file and copy if back again making sure that you preserve the right permisssions. What else... Let's see. try to reboot the system, this should always work :-) Yours' Sebastian On Mon, 3 Apr 2000 cpt.kirk at 1tree.net wrote: > flock doesn't show any processes locking the file.
