Hi, I have some serious problem with my Samba server in production environment. For information, I am running a samba 3.0.10-1.4E.2 under a kernel Linux version 2.6.9-22 with a RHEL 3.4.4-2. The problem is that I noticed in the log files the following errors : smbd[25842]: [2006/06/14 11:25:07, 0] smbd/oplock.c:request_oplock_break(1055) smbd[25842]: request_oplock_break: no response received to oplock break request to pid 25225 on port 33355 for dev = 16, inode 4720682, file_id = 2 Next ... 3 hours later another error appear : smbd[25842]: process_local_message: unknown UDP message command code (8003) - ignoring. smbd[25842]: [2006/06/14 15:00:40, 0] smbd/oplock.c:process_local_message(441) And this last one occured more than 200 times per seconds during 4 seconds and pull the CPU to 100 percent, with a smbd process at 99% : 25842 nobody 25 0 12864 3740 3112 R 99.7 0.1 10053:47 smbd By the way, since this time samba connections seems anormaly slow ... So does anyone know something about this problem ? Is there a way to avoid this ? thanks
