Of course. We upgraded to the last kernel available (in that moment) for RHEL4: 2.6.9-34.ELsmp The release notes mentioned that some important issues related to locking in client NFS environment were missing in the kernel included in the distribution.

Darn. That's the same kernel I'm running. Must not be my lucky day.

Hi all. We also had problems with client NFS locking using RHEL4, kernel 2.6.9 Some of them were solved updating the kelnel from RedHat. Hope this helps.

Hi Luis.

Can you tell me which kernel you upgraded to?

Thanks.

I'm running beta7 on two machines, with maildir on NFS. I have lockd running on all machines. I've found that Dovecot is highly unstable with NFS when accessing a mailbox on more than one machine at the same time.

Both dovecot machines have:

mmap_disable = yes lock_method = fcntl

NFS is version 3, exported from a third linux machine. All machines are running 2.6.9 kernel.

Any ideas what's going wrong here?
