Cyrus gurus:
I'm in the process of wrapping up the RPM package
of cyrus-imapd version 2.0.11.
In previous versions the package installation process
created an empty mailboxes.db file in /var/imap
(which is the value if the "configdirectory"
directive in /etc/imapd) and this didn't
caused problems.
In my tests I have found that in 2.0.11
imapd dies dumping a core file when you
connect, say with cyradm to create the
first mailbox, to the imap port.
The relevant portion of the logfiles follows:
--------------
master: unable to change limit of file descriptors available
master[17893]: process started
ctl_mboxlist[17895]: running mboxlist recovery
ctl_mboxlist[17895]: done running mboxlist recovery
master[17893]: no service 'pop3s' in /etc/services, disabling pop3s
master[17893]: no service 'sieve' in /etc/services, disabling sieve
master[17893]: ready for work
ctl_mboxlist[17901]: checkpointing mboxlist
PAM_pwdb[17904]: (su) session opened for user cyrus by (uid=0)
imapd[17906]: DBERROR: opening /var/imap/mailboxes.db: No such file or
directory
imapd[17906]: DBERROR: opening /var/imap/mailboxes.db: cyrusdb error
PAM_pwdb[17904]: (su) session closed for user cyrus
--------------
I think ctl_mboxlist, configured as follows
in /etc/cyrus.conf,
--------------
START {
# do not delete these entries!
mboxlist cmd="ctl_mboxlist -r"
...
}
EVENTS {
# this is required
checkpoint cmd="ctl_mboxlist -c" period=30
...
}
--------------
interprets the zero-sized file as corrupt and then
deletes it.
I have modified the post-install process
so it creates an empty (0 records) mailboxes.db
in the following way:
su cyrus -c "echo -n | /usr/cyrus/bin/ctl_mboxlist -u -f
/var/imap/mailboxes.db" 2> /dev/null
Can somebody with more experience in db3/cyrus IMAPd
tell me if I'm in the good way or doing something dumb ?
PS: This approach seems to fix the
imapd-dies-right-after-the-first-connection problem
TIA, and as always excuse me for my english.
