Solution Verified - Updated -

Environment

  • Red Hat Satellite 5.x

Issue

  • HTTP 500 (Internal Server Error) when trying to add errata or clone a channel with all errata
  • Following errors observed in /var/log/httpd/error_log:
[Thu Mar 01 11:36:16 2012] [error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header
  • Deleting a clone channel fails with:
503 Service Temporarily Unavailable
  • Cloning the channel fails with time out error on Satellte WebUi.

Resolution

  • In /etc/httpd/conf/httpd.conf, increase the Timeout directive:
Timeout 500
  • Increase Tomcat's session_timeout field, by editing /var/lib/tomcat6/webapps/rhn/WEB-INF/web.xml:
 <session-config>
    <session-timeout>90</session-timeout>
  </session-config>
  • Modify the AJP timeout by editing the file '/etc/httpd/conf.d/zz-spacewalk-www.conf':
   ProxyTimeout 1800
  • Restart Satellite services:
# rhn-satellite restart

Root Cause

  • httpd timed out while waiting for a response from Tomcat.
