Orca error when displaying openX ads

I have installed Dolphin 6.1.4 and also, OpenX ad server, to manage banners within my site.

Both working fine together, except for Orca. I got rid of the 'promo text' in the site template and instead I put piece of javascript - OpenX zone invocation. It works fine on all Dolphin pages, banner just below menu is displaying fine.

But if I open Orca, there is only blank screen. Server error log saing PHP Fatal error: Allowed memory size of ... exhausted ... in /orca/inc/util.inc.php on line 236

Orca is working fine when I remove that javascript from the template. Any ideas what is wrong?

Changed invocation type from 'javascript' to 'iframe' and everything works fine - strange that piece of javascript (which works great on other pages!) can crash Orca....

I have had a lot of problems with OpenX and Orca. Has there been any further development on this issue?
