Lack of memory

When I try to push, I’m getting following warning, but I can not find the way to remedy the announced lack of memory. Can someone help me to solve the problem? Thanks!

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 23991443 bytes) in /fs5b/fivefilters/public/kindle-it/libraries/flourish/fEmail.php on line 1161

Hi Jose, I’m assuming you’re trying to process a very large page in Push to Kindle. The service is intended for regular web articles - which usually never reach the memory limit. We’re looking into improving support for larger pages, but until we do you will likely encounter this error when processing very large documents with Push to Kindle.
