[wp-hackers] Size limit on post.

[Dion Hulse (dd32)]

Neither. They're the number of times the regular expression library is  
able to backtrace, and the number its allowed to recurse, in a extremely  
simple expression, on a large peice of text, it'll only use very little,  
when you use a large piece of text, with a complex expression, it can  
often cause the backtracing to increase as it attempts to match the longer  
text.

Other than trial and error, Its not possible to say what value you'd need,  
or if its even caused by this.
