Is there a limit on how much data I can put in a WordPress database?

Hello,

I received this message after trying to post a page:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 606539 bytes) in /home/ —-/public_html/wp-includes/wp-db.php on line 501

Is there a limit as to how much data I can upload to the WordPress databases? Or do you think this is problem with my server?

Thanks,

Wade
