[Building Sakai] Losing pages from sites

[Matthew Buckett]

I don't think so, this can be reproduced with a jmeter script using one session.

I tried disabling the site cache
(cacheMinutes at org.sakaiproject.site.api.SiteService=0
) to see if that might be related but this causes the site-manage tool
to stop working completely:

org.sakaiproject.portal.api.PortalHandlerException:
