Looks like bad news. :(
I've run nfstest to look for problems. The output is attached. I'm not sure, but it looks like a bad nfs environment.

2.6.9 is old and there are several NFS bugs in older 2.6 kernels. So I'd try upgrading. I've really no idea what else could be the problem.

Is there any know issue about it on kernel 2.6.9 (centos)? Any other mount options I could try?
Thank you.

Dovecot is running on a linux machine (2.6 kernel). The nfs was mounted as: nfs rw,vers=3,proto=tcp,intr,nolock,noexec,rsize=8192,wsize=8192 0 0
After your hint we added the "noac" flag: nfs rw,vers=3,proto=tcp,intr,nolock,noexec,noac,rsize=8192,wsize=8192 0 0
But the error continues with differences of 120 and 60 seconds.
Thanks for the reply, gpg

The IT guy swears the clocks are sincronized.
the difference in the above message is exactly 120 seconds. Are they all 120 seconds?
I'm using dovecot 1.1.6 over NFS. Any thoughts?
What OS are you using on the NFS clients? Perhaps this is a caching issue, have you tried changing/disabling attribute cache timeouts?
