Hi, Adam-- On Nov 29, 2010, at 5:06 PM, Adam McDougall wrote: > I've been running dovecot 1.1 on FreeBSD 7.x for a while with a bare minimum of NFS problems, but it got worse with 8.x. I have 2-4 servers (usually just 2) accessing mail on a Netapp over NFSv3 via imapd. delivery is via procmail which doesn't touch the dovecot metadata and webmail uses imapd. Client connections to imapd go to random servers and I don't yet have solid means to keep certain users on certain servers. Are you familiar with: http://wiki1.dovecot.org/NFS Basically, you're running a "try to avoid doing this" configuration, but it does discuss some options to improve the situation. If you can tolerate the performance hit, try disabling NFS attribute cache... Regards, -- -Chuck
