Description Jan Hutař 2010-10-07 12:12:07 UTC

Description of problem:
There are strange error messages in /var/log/httpd/error_log which should not be there - we do not want any [error] messages there.


Version-Release number of selected component (if applicable):
Satellite-5.4.0-RHEL5-re20101001.1-x86_64-embedded-oracle


How reproducible:
always (seen it multiple times)


Steps to Reproduce:
1. Install Satellite - this seems to appear that the satellite produces this when is restarted as a last step of the installation process.


Actual results:
# less /var/log/httpd/error_log
[...]

Expected results:
No [error] messages in the error_log.

Comment 4 Jan Pazdziora (Red Hat) 2010-12-10 23:27:06 UTC

Jan, at the end of the spacewalk-setup, services are restarted. The spacewalk-setup then tries to access the server a couple of times in the wait_for_tomcat method, waiting for tomcat to finish loading. The problem with tomcat is that its init script returns upon start even if tomcat is still not ready to serve the content.

So what the error messages mean are actually probes that try to access the server, before telling you that the installation passed alright.

Comment 5 Jan Pazdziora (Red Hat) 2010-12-10 23:28:20 UTC

The truth is, we could be able to address this by checking tomcat directly, and only once it's loaded, do a HEAD request via httpd.

Taking for more investigation.

Comment 6 Jan Pazdziora (Red Hat) 2010-12-13 19:21:19 UTC

Fixed in Spacewalk master, bd0ff15cb3f86cefdcd1c899852bd404bb958aa0.

Comment 7 Jan Pazdziora (Red Hat) 2010-12-13 19:38:54 UTC

Tagged and built as spacewalk-setup-1.3.1-1. It will be in tomorrow's Spacewalk nightly composes.

Comment 13 Jan Pazdziora (Red Hat) 2012-07-12 13:19:05 UTC
