Good day for all. Ive got newly installed linux box with APACHE
1.3.27PHP/4.4.4 mod_ssl/2.8.28 OpenSSL/0.9.8d
Some times in a day in httpd error_log appears lines
child pid ***** exit signal Segmentation fault (11)
I decided to get a core dump.
After using gdb utility, i've got the following output

The next step is to identify this problem. What it could be?
Thanks in advance!!
