[Spacewalk-list] 2.0 Upgrade - serious performances issues during daily "diff profiled config files and deployed config files"

[Sebastien Leterrier]

Hello Thomas,

Thanks for your answer!

I have just checked my configuration files size: the largest we manage are 60KB big. I also did some digging and to my understanding, unless you specify custom values for maximum_config_file_size and web.maximum_config_file_size in rhn.conf, the default maximum value is 128KB. Is that correct?

For the time being, I have disabled the scheduled job "compare-configs-default" which runs "compare-configs-bunch" every day at 23:00. Our setup is stable again but it is missing one of the key functionality. Bonus questions here: is there any way I could create new bunch that could be ran via the scheduler? Is there a way to view/edit predefined bunch(es)? 
I also tried to manually run a diff against all registered clients: as you could expect, the end result is the same. However, if I run a manual diff against ~30 clients at a time, everything runs fine.

Hello Sebastien,

CompareConfigFilesTask.java was last changed  in July 2011 (changing copyright years). 
It's super class was changed recently, but the changes have no effect on the configuration files comparison. 

How large are your configuration files?
Do you have many of them that are larger than 1MB?
