The quoted error message coincided with an very high load average (it's hovering around 4) and this additional error message:  

Jun 26 11:46:11 server imap(user): open() failed with file /home/user/Maildir/.INBOX/.imap.index: Permission denied

I'm using Red Hat 4.

What's the kernel version on this system?
I recall having strange VFS problems with older kernels (around 2.6.10).
Basically, it means that any application tried to get a lock and it was granted, but before the application could do the lock, it was acquired by someone else (typical race condition).

Is this directory on a NFS share or something like this?

Kernel: 2.6.9-34.ELsmp

The directory is indeed on an NFS share, and is our mail server as well.  I inherited the NFS configuration, it spans a large company and it's definitely not entirely standard and there is occasionally some wonkiness.  I sometimes encounter locks, notably fcntl.

The VSF issue has stuck me, so far.

OK, then you would have to either live with it or upgrade your kernel to something newer (2.6.20 has finally fixed this issue, AFAIK).

Thanks again!  I'm sure I'll have plenty more to report, soon.
