Hi Timo... It's happens some strange issue with my maildir using NFS. If i use a Local Hard disk, i don't get any of this messages about memory error. Jan 12 10:57:50 brc dovecot: imap(alex at exemplo.com.br): Error: opendir(/storage/nfs/3/emexis/messages/ exemplo.com.br/alex/Maildir/.Drafts/new) failed: Cannot allocate memory Jan 12 10:57:51 brc last message repeated 4 times Jan 12

We're running dovecot 2.2.15 with pigeonhole 0.4.6, in a clustered environment, nfs with proxy and backend on all servers. I've been seeing some odd errors from lmtp: Error: mremap_anon(127930368) failed: Cannot allocate memory It seems to affect specific users, but it doesn't seem to manifest in any particular way; no user complaints. Just the occasional log message. I would guess this is a bug? I'm open to suggestions and I'd be happy to post config if somebody h...

Hey folks.

Just the occasional log message. A config would always be useful, but I can venture a guess. Perhaps the affected users have a...

...em and let > dovecot rebuild them. I seem to recall these cache files ballooned in size when I did some doveadm search queries -- under some circumstances some headers fetches are cached for later searches, which may explain the growth over time as clients do mailbox searches. As for Solaris10 mremap_anon() space failures, I'm a litte hazy on memory mapping and shared memory, but I wonder if this has anything to do with kernel maximum shared memory limits. I know that for some of our Solaris 10 servers, I had to up these values in /etc/system to get some of our services to work. Joseph Tam &lt...

...'s a "risky" sort of thing to do in a server process, even if 8GB RAM systems do seem to grow on trees. I intend to put this to work in a large installation (>10K users), so this IS of some concern for me in the long-term.
