    Description

      When having to send lots of notification emails the Job Scheduler seems run out of memory. Since we are currently reorganizing the structure, this has become a quite regular case, which is a little annoying, since I have to restart the XWiki application. Unfortunately the application server does not like this at all and XWiki becomes unresponsive. For now I have to disable the email jobs.
