Could it be that it the Zend Optimizer that's causing >this problem? Anything is possible... The Optimizer *does* have to examine the source code and do things with it. I would guess that there are some analyses that might be recursive and could overflow the stack... You *MIGHT* try installing the Optimizer on a Dev box and turning on *ONE* opitmization group/feature at a time and then pounding on that Dev server with 'ab' until you narrow down which optimizations are the trouble-makers. Why in the *WORLD* do you have hundreds of includes, though? You do realize that including a hundred include files is incredibly slow, right?... You may be able to drastically improve performance if there's any way to combine those files... To test this: Make a list of a sample of a 100 files that get included in one page hit. Then cat all those files into 1 big file. Strip out all the 'include' calls. A/B compare the real page and the big fat page under stress. -- Like Music? http://l-i-e.com/artists.htm
