Memory Exhaustion - SimplePie?


I get memory exhaustion errorys for simplepie

'Fatal error: Out of memory (allocated 32768000) (tried to allocate 1966080 bytes) in /home/domainname/public_html/wp-includes/class-simplepie.php on line 5410'

when i try to process a feed within AutoBlog.

I tried raising php memory limits both in wp constant and php.ini but no progress.... Any other solutions to help with this? Thanks
