Description thomas mayr 2011-05-05 11:13:25 UTC

Description of problem:

if you try to sync your channel with the web gui you will see the message:
"The scheduling service appears down. Please contact your Satellite administrator."
and the buttons are disabled.
if you use the command line the repo-sync works.
if you check the state of taskomatic:
 /etc/init.d/taskomatic status
=> RHN Taskomatic is not running.

if you now start it with /etc/init.d/taskomatic start its starting and running for a while and then it stops. in the log file

/var/log/rhn/rhn_taskomatic_daemon.log you will see:

Aligning under space16.

Comment 2 Tomas Lestach 2011-08-05 11:46:30 UTC

"Unsupported major.minor version 49.0" error means, you use an older java version than java the class was compiled with.

This isn't a Spacewalk bug, but java incompatibility issue.

I suggest to run:
$ alternatives --config java
to make sure 1.6 is used.

Closing as NOTABUG.
