I have also had this problem, and asking about it here provided no help.

Mine seems to be related to abnormally high numbers of instantiated
objects and large amounts of reference-passing. Occasionally Apache
children will die (with the error you've described), or spin out of
control and hog the CPU for a while (Apache 1.3.27, Red Hat 9, PHP 4.3.2).
I have not been able to track down the problem, though I did attempt to
re-create it using the command-line PHP interpreter to write Apache out of
the picture, and was not able to reproduce the errors.

I've tried to route around them somewhat, and have been moderately
successful, except when they bump my CPU load to 100%. :-P
