After a while I decided to have a look into the server logfiles …. so I learned that postfix wasn’t able to deliver mails via lmtp cause of:

Oct  7 07:45:56 post cyrus/lmtpunix[307]: DBERROR db4: Logging region out of memory; you may need to increase its size
Oct  7 07:45:56 post cyrus/lmtpunix[307]: DBERROR: opening /var/lib/cyrus/deliver.db: Cannot allocate memory
Oct  7 07:45:56 post cyrus/lmtpunix[307]: DBERROR: opening /var/lib/cyrus/deliver.db: cyrusdb error
Oct  7 07:45:56 post cyrus/lmtpunix[307]: FATAL: lmtpd: unable to init duplicate delivery database
Oct  7 07:45:56 post cyrus/master[754]: service lmtpunix pid 307 in READY state: terminated abnormally

Seems like this can be fixed with:

/etc/init.d/cyrus2.2 stop
cat< /var/lib/cyrus/db/DB_CONFIG
set_cachesize 0 2097152 1
set_lg_regionmax 1048576
EOM
/etc/init.d/cyrus2.2 start

Looking more closer into the logs, it turned out that this trouble started last night when I connected with a client running the soon to be released Ubuntu Oneiric Ocelot using the new kmail2.

So it looks like the KDE/Ubuntu folks broke again kmail (or any KDE subsystem), as it also has troubles when migrating over from kmail(1) and it looks like it’s not able to access most of the imap subfolders. Well done!

We are running the plattform for the online streaming of Lohengrin live from the Bayreuth Festival Theatre on Sunday, 14th August 2011. Usually we are coming together around noon and having a BBQ while keeping all the stuff up and running.

To get back into this millenium, we (yes, my girl and me) are at the Highfield festival the weekend afterwards. I guess you can find me at the “white stage” or at camp site. Keep on rocking!

As my lovely girl used to be a teacher, she has some time off at that period. So she left me with our kids yesterday to visit the grandparents.
It was two hours after leaving, when I was really surprized that I was sitting around and thinking about what to do next, as normaly the weekend are family time.
So I decided to take my bike and a paper map to get of for a trip. Since some years, I usually use my bike to escort the girls or when going to work, which is just a 5 minutes ride, so I thought that would be a great opportunitiy.
I took a backpack with raining clothes, mounted the bike helmet on it, in case I needed to go cross country, some water and my music player.
It was a great ride, beside that I realized I’m not in the same condition as some years ago. Unfortunately this will likely not change in the next 12 mounth, as we have some projects in the queue we need to deal with. Hopefully we will solve that satisfactorily and have a bit more spare time afterwards.

Anyways .. 27,65km in 1h40 is not so bad, as it was hot and humid.

To make it short, the following should work:

    # grep GRUB_CMDLINE_XEN /etc/default/grub
    GRUB_CMDLINE_XEN=”pci=use_crs”
    # update-grub

    It took me two workdays to discover this solution for a DL180G6. Anyways … I’m still having trouble on a DL160G6 when booting the hypervisor, suggestions are welcome.

As always, it was a joy to be at this event. We had great discussions and talks with guests and exhibitors, I also enjoyed a small number of lectures. The booth did run well, beside some quirks. Some pictures can be found here.

    Today I uploaded a new postfwd package which ships also the postfwd2 script, a prefork server version.
    I also started to orphan packages I’m not using anymore or having dead upstream. The first candidate was policyd-weight, fortunately Chris Butler took the package over.
    I’m happy to be the first uploader into squeeze-backports with …. icinga.

Many thanks to all who made this happen, I’m very proud!
    Also many thanks to the release team, ftpmaster, cd people, www-team, press folks and all who worked so hard today instead of having release party, to make it real.

As result of this, I started rolling out linux-image-2.6.32-bpo.5-xen-686 from bpo and backported xen and xen-common from testing:

    # dpkg -l | grep xen | grep bpo
    ii libxenstore3.0 4.0.1-1~bpo50+1 Xenstore communications library for Xen
    ii linux-image-2.6.32-bpo.5-xen-686 2.6.32-26~bpo50+1 Linux 2.6.32 for modern PCs, Xen dom0 suppor
    ii xen-hypervisor-4.0-i386 4.0.1-1~bpo50+1 The Xen Hypervisor on i386
    ii xen-linux-system-2.6.32-bpo.5-xen-686 2.6.32-26~bpo50+1 Xen system with Linux 2.6.32 on modern PCs (
    ii xen-tools 4.1-1~bpo50+1 Tools to manage Debian XEN virtual servers
    ii xen-utils-4.0 4.0.1-1~bpo50+1 XEN administrative tools
    ii xen-utils-common 4.0.0-1~bpo50+1 XEN administrative tools – common files
    ii xenstore-utils 4.0.1-1~bpo50+1 Xenstore utilities for Xen

    This fixed the problem of spontaneous reboots for all of the systems I have migrated …. until now! Last week I tried this solution on my private system and it failed in some way.

    A full dump of the syslog is also available. It looks like /etc/rcS.d/S03udev is hanging in some way .. the syslog for this looks like:

    Oct 29 20:51:07 mordor kernel: [ 17.728120] Code: 04 00 00 00 00 83 3c 24 10 74 32 77 0c 83 3c 24 08 0f 85 9f 00 00 00 eb 12 83 3c 24 20 74 30 83 3c 24 40 0f 85 8d 00 00 00 eb 35 <0f> b6 01 8b 54 24 20 89 02 c7 42 04 00 00 00 00 eb 79 0f b7 01

    The dom0 is there hanging in some way … I don’t have an exact way to get the system proceed from there … usually I need to wait some seconds and pressing ^C after a while will get the box up.
    Anyways … I remember there are some problems with udev >= 150 and older kernels, which is also documented in the squeeze release notes. Maybe there is also a problem with older udev and newer kernels? But why is this combination working on other systems? Booting linux-image-2.6.32-bpo.5-686 works without any issue anyways, so it seems xen related. Any idea is appreciated!
    UPDATE: I’ve also reported this via #602109.

This will be the next candidate for lenny-backports-sloppy.
    If you can’t wait, just grab the package from http://ftp.cyconet.org/debian/archive/bpo/icinga/1.2-1~bpo50+1/.
    If you are using nagstamon and thinking about upgrading to icinga 1.2, I backported a working version from subversion r151, which you can grab from http://ftp.cyconet.org/debian/archive/bpo/nagstamon/0.9.4r151.1~bpo50+1/.

    P.S. If you like nagios and/or icinga related software, there is a Nagios Maintainers Group and we would like to invite you, if you want to improve or extend the nagios/icinga ecosystem in Debian.
