hi

I have dovecot (1.0.alpha4-1) installed on a Debian sid amd64 machine (dovecot-imapd and dovecot-common). I am using this so that I can use both Mutt and something like Thunderbird to access my local Maildir folders. Sometimes it works fine. Sometimes when I try to access my mailboxes locally using Mutt, it hangs for a very long time (the bottom of the screen says "Selecting in..." (.in is the mailbox), and eventually gives me a blank mailbox with "(no mailbox)" at the bottom of the screen. In /var/log/mail.err I find lines like the following: Dec 3 06:39:02 localhost dovecot: child 4600 (imap) returned error 83 (Out of memory) Dec 3 06:44:03 localhost dovecot: imap(ric): pool_system_malloc(): Out of memory For example, it was working fine earlier this morning, but now I am unable to access the mailboxes and I'm getting the error messages in /var/log/mail.err.

I have the same problem with Thunderbird; it hangs and cannot access the mailboxes.

At my office I have dovecot (0.99.14-1) installed on a Debian sarge machine and it works fine.

I would appreciate any suggestions as to what to try or what to look for. My dovecot.conf file is very simple:

## Dovecot 1.0 configuration file protocols = imap listen = localhost ssl_disable = yes log_timestamp = "%Y-%m-%d %H:%M:%S " mail_extra_groups = mail protocol imap { } protocol pop3 { } auth default { mechanisms = plain passdb pam { } userdb passwd { } userdb prefetch { } user = root }

Thanks, Ric
