Segmentation fault at search_cron() Whenever I try to run cron on the search, using

drush php-eval 'search_cron();'


I get 'Segmentation fault' error. I have not this problem for any other tables. The site contains hundreds of text-heavy nodes. So I appreciate your hint to cope with the problem.
I believe that is a memory error. If increasing your memory limit doesn't work, you might get relief from lowering the number of nodes to index per cron run on the search settings page.

It could also be caused by running an out-of-date version of PHP.
