Hi, We still got problems with locking here. People don't get a hanging Word/Excel anymore but sometimes people get error messages from outlook that some other process has a byte range lock on a file. Now when I run smbstatus -B on the samba host I get tons of lines like this Byte range locks: Pid dev:inode R/W start size ------------------------------------------------ 4006 03a02:161e8 W 2147483540 1 4006 03a02:161e8 W 2147483481 1 4006 03a02:161e8 W 2147483521 1 3467 03a02:16338 W 2147483539 1 3467 03a02:16338 W 2147483559 1 3467 03a02:16338 W 2147483599 1 Those PIDs are no longer existent. None of them! The whole list of locks specifies PIDs that don't exist. Also the size bothers me, it's always 1 and start looks awfully close to signed max_int for 32bit. And it always is in that range. In the evening though, when nobody is there all locks are gone. Any ideas? Is this even the problem or might it be something completely different? Like wrong smbstatus output and the real problem lies somewhere else? I didn't read the source. Alex
