Jamu exits(1) when multiple instances are executed (such as if tvdb is down and one doesn't time out)

Can you try running it manually and see if there is any other output?
What was the last functional version?

Running the cronjob manually doesn't give more.
[..]
sudo run-parts --report /etc/cron.hourly
run-parts: /etc/cron.hourly/mythvideo exited with return code 1
[..]

Running /etc/cron.hourly/mythvideo manually doesn't give anything.
[..]
sudo /etc/cron.hourly/mythvideo
[..]

Looking at /etc/cron.hourly/mythvideo
[..]
#!/bin/sh
#Hourly massive update to ensure users see graphics coming in for upcoming recordings and current recordings
DIRECTORY=$(grep ^mythtv /etc/passwd | awk -F : '{print $6}')
if [ -f "$DIRECTORY/.mythtv/config.xml" ]; then
    su mythtv -c "/usr/bin/python /usr/share/mythtv/mythvideo/scripts/jamu.py -MW >> '/var/log/mythtv/jamu.log'"
fi
[..]

There is no time and date in /var/log/mythtv/jamu.log. So I only can attach it.

The last functional version was "0.22.0+fixes22564-0ubuntu1 (karmic)" I think.

At some point I can find this in the jamu.log. This could be a hint.

A "ps axf | grep myth" gives me that.

This is an upstream problem. The code uses sys.exit(True) where is should be using False and vice vera.

eg
                # Check if this is a Scheduled and Recorded graphics download request
                if self.config['mythtv_watched']:
                        self._downloadScheduledRecordedGraphics()
                        sys.exit(True)

is using True to indicate success. Switching the line above solves the problem for the cronjob but the whole code base needs a review.

This has been fixed upstream http://svn.mythtv.org/trac/ticket/7560

That change was committed 7 weeks ago. This build that the reporter is
running is quite fresh. He's also provided a "last functional" build to
base a comparison on from his broken one.

So after talking this over with the Jamu author, he suspects this is caused by prolonged outtages of tvdb. When a second instance of jamu spawns for the hourly cron job, it sees another running instance and causes an exit(1) code.

He will make this change upstream so that it will exit(0) instead if another instance is running.

This has been fixed upstream on their trunk repository. It will be available in the 0.23 autobuilds or later. This bug will be automatically closed when such a build is uploaded to the current Ubuntu development release (Lucid Lynx).

This bug was fixed in the package mythplugins - 0.23.0~trunk23567-0ubuntu1

---------------
mythplugins (0.23.0~trunk23567-0ubuntu1) lucid; urgency=low

  [ Jean-Yves Avenard ]
  * debian/control:
    - Add mythnetvision package

  [ Mario Limonciello ]
  * New snapshot.
  * Fixes Jamu crashes (LP: #507703, #459426)
  * Fixes jamu exiting w/ the wrong code (LP: #502051)
  * Fixes ttvdb.py crashes (LP: #508086)
  * debian/control:
    - Recommends libmath-round-perl for mythweb streaming support.
    - Drop mythflix support
  * debian/rules:
    - Drop mythflix support
  * debian/mcc-jamu, debian/mythvideo.install:
    - Add a Jamu MCC plugin that's only installed if mythvideo is installed.
      (LP: #516226)
  * debian/control:
    - Mark mythvideo as enhancing MCC.
  * Convert package to v3 w/ quilt
  * Convert package to use dh7
  * Drop mytharchive-data package. Just put all that stuff in mytharchive.
    mytharchive-data has no functional purpose as a standalone.
