[kune-commits] [Kune - Defect #525] SiteMap generation is not working properly in large sites

Mon Apr 1 09:56:40 CEST 2013

Issue #525 has been updated by Pablo Ojanguren.

So problem comes from a SELECT COUNT(*)... (SiteMapGenerator.countNotClosedGroups(SiteMapGenerator.java:160))
We could start thinking on hibernate-pool configuration problem.
