Out of memory error

i have this site which keeps on throwing out of memory error based on the error logs. sad thing is i cant reproduce the OOM error both on dev site and production s开发者_高级运维ite.

i checked the logs and found out that this only happens when bots crawl the pages throwing the OOM error or if the pages are accessed from google search results.

i would appreciate it if anyone could give me any advice on this. thanks

A common cause of this problem is bots trying search terms; if you have a search function on the site, you may want to add it--or any other pages that seem to be having the OOM to the Disallow section of your robots.txt .
