Problems with Cron after updating to Drupal Core 7.41

[albertocottica]

"After other bugs have been fixed, only edgesense keeps making problems. Issue
is an incomplete implementation of edgesense_cron, which is using hook_cron()
directly. It should use Queue API instead, as documented on the code.

Changing the PHP memory limit to 1024 Mb on the server overcomes the issue,
but a new issue for this performance killer of edgesense_cron() should
nevertheless be open." http://edgeryders.eu/en/comment/21381#comment-21381
