Comments:
Output buffering indeed cannot be used inside output handler functions. However, the
code that handled that error situation contained a bug that caused PHP to enter an
infinite loop. This bug is now fixed (although the limitation of not being able to
use output buffering inside output handlers still applies)

Well, the problem is that we have many virtual hosts on that server, each using it's
own log file...
I can confirm that the gdb trace for ALL the many dead process, which are in running
state, gives the three lines:
#0 0x4012c23e in chunk_free ()
#1 0x4012bfaa in __cfree ()
#2 0x80fbcbf in shutdown_memory_manager ()
(it happened this morning too)
Is there some way to know which script was executing just before the child died,
please tell me!

It would help a lot to track this down if you could find
out if this happens by running some script.

I'm using php 4.0.7-dev (downloaded from the CVS tree), Apache 1.3.20 on a P3 600 1
Gig RAM.
After some hours that the server is running, in no particularly loaded confdition, CPU
and memory utilization grows abnormally, making the server unusable.
"top" shows that 4 o 5 httpd processes are eating 20% CPU each, and are all in
"running" state. I managed to attach a gdb to one of these processes, and here's the
result:
Attaching to program `/usr/local/apache/bin/httpd', Pid 21784

This is all I get. I saw MANY MANY bug reports with similarities to this one in the
db. The only solution is stopping and restarting apache. In apache's error_log i get
many lines with "child xxx still did not exit...sending a SIGTERM" and "child xxx
still did not exit...sending a SIGKILL" as soon as i stop it.
Let me know if I can make something to help you out more!
