Question

I’m using CFPropertyList from https://github.com/rodneyrehm/CFPropertyList for handling content I add with PHP.

It all worked fine, but now that all content is added my file has about 700KB which is not big but seems big enough to let Apache crash on trying to save a file.

child pid 1278 exit signal Segmentation fault

I see in CacheGrind that a lot of time in my application is taken by calls to CFPropertyList->import() and CFDictionary->toXML() so where could be the bottleneck there???

Am I making to many changes at once? Should I load() and save() inbetween changes more to avoid having too many changes saved at once?

Any clue?

When you implement a searchNode() function in an document of unknown size, you should always use a “depth” parameter to avoid stepping down in the document and calling your function enormous times in a recursive loop.

Because that creates infinite loops that also cause a segfault in PHP which don’t end in a fatal error or warning.
