 yes i see, sorry i missed it, but looking at your backtrace i dont
 wanna
 speculate

 however why are using nfs for only one server ?, and why have you set

i am not convinced nfs is a good choice, but however it should work with
right config

Hi Robert,

I'm alreay running 2.1.17, was a typo error:

I'm using NFS for HA and future scalability, I have two pop/imap/mx
servers in Active/Passive configuration.


perhaps switch to drbd


I was using DRBD, on these servers, a year ago. But the data store was 
full and for better future scalability I prefer to switch to an external 
NAS.




I set maildir_very_dirty_syncs for "Optimizazion" since only Dovecot
accesses cur/ directory (for POP/IMAP/Delivery).


i leave this to Timo, i am not using it

Yes, you're right, but this installation could grow very quickly in the 
next few months and I have to be ready to add new servers.
