Can you post the complete stack trace of the tomcat-container from the logfile of tomcat? Maybe there is something overlooked that someone has already seen?

Thanks.  In working through things I did find it griping that the database schema was at 94% of the allocated space.  I’ve got the DBAs looking at that now.  Regardless of if it’s causing the actual problem it should probably be addressed.

Yes, tomcat is throwing a stack-trace. Check the file /var/log/tomcat/<something>

How about the firewall, and ssl certificates?
Are there any clues in the log files?

Try spacewalk-service status and look for clues there

Yes, that was one of the first things I tried.  Still no joy.

Have you tried disabling SELinux, and restarting the service?

I've previously run into several issues with the default policy and needed to modify it to allow SELinux and Spacewalk to co-exist.

Thanks!,

To all – I’ve got an existing Spacewalk 2.7 server running on Oracle Linux 6.10.  I’m wanting to move off of 6.10 and go to 7.X (I’d go with 8.x but everything I’ve found says that all Spacewalk features are not supported on 8).  The plan is to get the 2.7 running on the 7.x server and then upgrade Spacewalk to 2.10.  I’ve got the new server built and Spacewalk installed but when trying to access the web interface all I’m getting is the Spacewalk banner above a white screen – no login prompt or anything.  It’s also takes a while for the page to load as well, much longer than the original server.  I’ve been working with Oracle tech support and not getting anywhere.  I’m hoping that someone here might have a suggestion where to start looking to solve the problem.

TIA,
Paul
