Hi All,
I am having an odd issue with the panel wizard in my test and prod
instances of XWiki. The users are trying to click on "Panel Wizard" via
"Administer this Wiki" and the system spikes to 25% CPU but never yields
results. Later, they try again, another 25% CPU and no results....
ultimately they keep trying until I start getting administrative alerts
that the system is overwhelmed. To recover, I need to stop/start the
application. However, that only allows the application to function until
they do the same thing again. This is a critical task for them to add the
necessary navigation to their wiki.
Anyone had a similar experience?
The panel wizard renders all the panels and so if you have a panel
that uses a lot of resources (CPU/Memory) it will slow down or even
block the panel wizard. From my experience, the panels from the
standard XAR that cause problems on large wikis are Panels.Navigation
and Panels.SpaceDocs because they don't limit the number of pages
displayed and both are loaded synchronously (when the page loads, so
no AJAX). The description of Panels.Navigation warns you about this:
"However when your wiki grows you'll usually want to replace it with
your own fixed navigation".
Hope this helps,
Marius
Any ideas on how to troubleshoot this further?
Thanks,
Chris
