It seems to me that reason for this segfautls is similar to bug #370375
hangups. At least depending on php version apache hangs or segfaults but
not both.

Try disabling Eaccelerator and report if those crashes happen as well.
Most crashes I have seen were related to Eaccelerator.

EAccelerator disabled, but apache still crashes.

some additional information from apache error.log:

Ok, now try disabling those two nonstandard modules.  (Keep eaccel
disabled).  My next suspect would be memcache since it does store
objects in memory and that segfault is in memory management.

Hmmm, ok, looks like you have found bug in PHP4 :-).

Are you able to test same configuration with unstable version of php4
4.4.4?  F.E. in chroot?

Build php 4.4.4-1 and apache2_2.0.55-4.2 from source with additional
debugging information.

Lots of Segmentation faults in error.log but no core dumps.
Still trying to get one.

The libapache2-mod-php4 package has been removed from Debian testing, unstable and
experimental. I am reassigning its bugs to the libapache2-mod-php5 package. Please
have a look at them, and close them if they don't apply to
libapache2-mod-php5 anymore.

this is not the first time someone has done a mass-reassignment on old php4 
bugs.  blindly reassigning bugs from php4->php5 is not the proper protocol 
here.  just because php4 will not be in lenny does not mean that it is not 
still in debian.  furthermore, if the bug affected php5 it should have 
already been cloned to php5.

Version: 6:4.4.6-2+rm

You filed the bug http://bugs.debian.org/386041 in Debian BTS
against the package libapache2-mod-php4. I'm closing it at *unstable*, but it will
remain open for older distributions.

For more information about this package's removal, read
http://bugs.debian.org/428266. That bug might give the reasons why
this package was removed and suggestions of possible replacements.

Don't hesitate to reply to this mail if you have any question.

Thank you for your contribution to Debian.
