Hello, I am running a samba file server (2.0.7) on a linux box (2.2.14). The samba server seems very slow at certain times and I believe this has something to with locking. This is what I get in the logs: ------------------------------------------------------- Apr 28 08:27:37 samba smbd[14775]: [2000/04/28 08:27:37, 0] smbd/oplock.c:oplock_break(976) Apr 28 08:27:37 samba smbd[14775]: oplock_break: receive_smb timed out after 30 seconds.

The "reply_lockingX: Error :" comes only from Win2K machines. How can the performance of the server be improved and how these timeout can be avoided? Thanks in advance! Ralf
