Description Tasos Papaioannou 2011-04-12 21:37:36 UTC
Description of problem:

On Satellite 5.3 running on RHEL 4 AS (32-bit or 64-bit) and with the latest installed packages available from RHN, the taskomatic service fails to start. 

Version-Release number of selected component (if applicable):

spacewalk-config-0.5.9-16.el4sat


How reproducible:

100%

Steps to Reproduce:
1. Install Satellite 5.3 on RHEL 4.
2. Update to latest spacewalk* packages from RHN.
3. Restart rhn-satellite service.
  
Actual results:

Taskomatic fails to start. From /var/log/rhn/rhn_taskomatic_daemon.log:

[...]
ERROR  | wrapper  | 2011/04/12 11:32:29 | Startup failed: Timed out waiting for signal from JVM.
ERROR  | wrapper  | 2011/04/12 11:32:29 | JVM did not exit on request, terminated
FATAL  | wrapper  | 2011/04/12 11:32:29 | There were 5 failed launches in a row, each lasting less than 300 seconds.  Giving up.
FATAL  | wrapper  | 2011/04/12 11:32:29 |   There may be a configuration problem: please check the logs.
STATUS | wrapper  | 2011/04/12 11:32:29 | <-- Wrapper Stopped

This is because taskomatic receives an HTTP 404 error when requesting api.getVersion from /rpc/api. In /var/log/httpd/error_log:
[...]
[Tue Apr 12 11:32:19 2011] [error] [client 127.0.0.1] File does not exist: /var/www/html/rhn/rpc
[Tue Apr 12 11:32:23 2011] [error] [client 127.0.0.1] File does not exist: /var/www/html/rhn/rpc
[Tue Apr 12 11:32:27 2011] [error] [client 127.0.0.1] File does not exist: /var/www/html/rhn/rpc


Expected results:

Successful Taskomatic startup and URL redirection by Apache httpd.

Additional info:

This is an only when the Satellite is on RHEL 4. The changes introduced in https://rhn.redhat.com/errata/RHSA-2011-0434.html to /etc/httpd/conf.d/zz-spacewalk-www.conf appear to be responsible. Backing out the changes and restarting httpd resolves the taskomatic startup issue.

I confirm the issue. It affects not only taskomatic but all frontend XMLRPC API.

Comment 2 Jan Pazdziora 2011-04-13 11:47:31 UTC
Tasos,

could you please check that if you revert the zz-spacewalk-www.conf to the (broken) version from spacewalk-config-0.5.9-16.el4sat, and then apply the following patch, it will address the issue as well?

Hi Jan,

Yes, the patch resolves the issue as well.

Thanks,
Tasos

Comment 5 Jan Pazdziora 2011-04-13 12:35:06 UTC
The problem is not only taskomatic but also any frontend XMLRPC API calls and display of kickstart files, like the .../ks/cfg/org/... URL on the Kickstart Details > Bare Metal Kickstart page.

Comment 8 Jan Pazdziora 2011-04-14 07:28:28 UTC
Please note that we are only releasing the new packages for RHEL 4, not RHEL 5. 

Of course, if would be good to QA verify that in fact, the problem is not present on Satellite 5.3.0 on RHEL 5 (nor on Satellite 5.4.0).
