Thats interesting. A diff would be useful if you have one.
What's the best way to set these settings? At the moment I'm exporting them just before I use spawn-fcgi (from lighttpd), but even though I've set it to a low number (10) I don't think its being honoured. I'm running CentOS5, if that's any help.
If I can't find a suitable work-around for this I may have to switch to apache with php compiled in - something I don't really want to do as I'm finding working with nginx to be a great experience.

Thats a common issue (at least for me). Although php leaks itself with every version less there are still quite a bunch of extensions outside that dont handle the memory bits the right way.
As a workarround I use this patch http://devzone.zend.com/content/patch/pat38.txt
Its pretty old and made for php4 but with little tweaks you can apply also to php5 (I could make a diff and throw in here). The basic idea is you have an extra setting PHP_FCGI_MAX_RAM_MB - you can limit at what memory usage the php child should handle the last request and die (so the master process can spawn a new one - similar to PHP_FCGI_MAX_REQUESTS ).
This solution is better because you dont accidently kill a process which is in a middle of generating a response.

Further to the email below, I'm still having problems with PHP5 fastcgi and nginx. I'm finding that php slowly takes up 100% of the available memory and starts to drop connections at around 70%. At the moment I've got monit restarting the fastcgi processes when the memory usage hits 70%, but this isn't optimal as the scripts I'm running shouldn't take anywhere near that on a virtual server with 300MB dedicated ram.
I'm wondering whether anyone else has come across the same problem running php5 fastcgi who has managed to find a fix or work-around?
