Zope freezes when calling qseo_without_additional_keywords=1

Posted by mukruthi at March 26. 2008

Dear All,

We have installed QSEOoptimizer on Plone 2.5.3 Our zope instance used to freeze, so we installed deadlock debugger to check why it got frozen. This is the out put of the debugger.

What is the cause of this?
