Hello list,

I have a strange problem with dovecot and quota. The error message is
not obvious...

After a couple of seconds when I try to start dovceot, I get this: root@taleira:~# /etc/init.d/dovecot start Alarm clock

If I uncomment the "imap_quota and quota" in dovecot.conf everything
seem to work fine:

protocol imap { listen = *:143 ssl_listen = *:993

problem pa taleira01: konstigt...

#mail_plugins = quota imap_quota mail_plugins = }

I can't really figure out what's wrong. There's nothing in the log and
dovecots error message is not so talkative. It took a while to figure
out that it was the quota that caused the problem. I guess there is
something with the underlying FS, but all kernel modules are loaded as
far as I know. The maildir is on a nfs-mounted disk. The whole system
is on a XEN machine and I have multipe copies of this image running on
other machines with no problem.

Strace gives me:

st_size=60, ...}) = 0 open("/var/run/dovecot//login", O_RDONLY|O_NONBLOCK|O_LARGEFILE| O_DIRECTORY|0x80000) = 4 fstat64(4, {st_mode=S_IFDIR|0750, st_size=60, ...}) = 0 getdents64(4, /* 3 entries */, 4096) = 88 lstat64("/var/run/dovecot//login/ssl-parameters.dat", {st_mode=S_IFREG| 0644, st_size=230, ...}) = 0 getdents64(4, /* 0 entries */, 4096) = 0 close(4) = 0 geteuid32() = 0 pipe([4, 5]) = 0 fcntl64(4, F_GETFD) = 0 fcntl64(4, F_SETFD, FD_CLOEXEC) = 0 fcntl64(5, F_GETFD) = 0 fcntl64(5, F_SETFD, FD_CLOEXEC) = 0 dup(2) = 6 fcntl64(6, F_GETFD) = 0 fcntl64(6, F_SETFD, FD_CLOEXEC) = 0 clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID| SIGCHLD, child_tidptr=0xf7e666f8) = 3343 close(6) = 0 close(5) = 0 alarm(5) = 0 wait4(-1, 0xffbd7e9c, 0, NULL) = ? ERESTARTSYS (To be

Finally, my system is:

root@taleira:~# dovecot --version 1.1.4 root@taleira:~# uname -a Linux taleira 2.6.26-1-xen-amd64 #1 SMP Sat Nov 8 21:20:04 UTC 2008
x86_64 GNU/Linux

Any ideas?
