Bug description: Segfaults due to possible memory leak??
Under 4.0.6, my apache processes start segfaulting with
the following problem after running (stable) for a period
of time:
[Tue Aug 7 16:53:30 2001] [notice] child pid 7139
exit signal Segmentation fault (11)
Once this starts happening, it continues until i kill and
restart the server. It will then run fine for some time,
then happen again. The period of time that it runs stable
decreases as hits increase ..
Running with --enable-debug I get the following in the
apache error log (I had issues generating a gdb backtrace,
but if needed I can attempt again):
/usr/www/thinkquest/common/nav_menu.inc(330) : Fatal error
- Allowed memory size of 12582912 bytes exhausted at
../../Zend/zend_opcode.c:48 (tried to allocate 184320
bytes)
/usr/www/thinkquest/common/scripts.inc(3062) : Fatal error

../../Zend/zend_opcode.c:48 (tried to allocate 11520 bytes)

... and similar, over and over again.. however the script
that it occurs in, and the line, are always different..
I tried increasing the amount of memory allowed per
script, but it just uses all that up too..
As a note... everything runs fine under 4.0.5 ....
I have cvs updates up to July 20.. The configuration
parameters I used are:
"../configure" \
"--prefix=/usr" \
"--with-apxs=/usr/bin/apxs" \
"--with-regex=system" \
"--with-config-file-path=/etc/php4/apache" \
"--disable-rpath" \
"--enable-debug" \
"--enable-memory-limit" \
"--enable-calendar" \
"--enable-sysvsem" \
"--enable-sysvshm" \
"--enable-track-vars" \
"--enable-trans-sid" \
"--enable-bcmath" \
"--with-bz2" \
"--enable-ctype" \
"--with-db2" \
"--with-ndbm" \
"--with-ldap=/usr" \
"--with-oci8=/usr/oracle/product/8.1.6" \
"--enable-sigchild" \
"--enable-exif" \
"--enable-filepro" \
"--enable-ftp" \
"--with-gettext" \
"--enable-mbstring" \
"--enable-mbstr-enc-trans" \
"--with-pcre-regex=/usr" \
"--enable-shmop" \
"--enable-sockets" \
"--enable-wddx" \
"--with-xml=/usr" \
"--with-expat-dir=/usr" \
"--enable-yp" \
"--with-zlib" \
"--without-pgsql" \
"--disable-static" \
"--with-layout=GNU" \
"--with-curl=shared,/usr" \
"--with-dom=shared,/usr" \
"--with-gd=shared,/usr" \
"--with-jpeg-dir=shared,/usr" \
"--with-xpm-dir=shared,/usr/X11R6" \
"--with-png-dir=shared,/usr" \
"--with-freetype-dir=shared,/usr" \
"--with-imap=shared,/usr" \
"--with-mcal=shared,/usr" \
"--with-mhash=shared,/usr" \
"--with-mysql=shared,/usr" \
"--with-sablot=shared,/usr" \
"--with-snmp=shared" \
"--with-sybase-ct=shared,/usr" \
"--with-ttf=shared,/usr" \
"--with-t1lib=shared,/usr"
The extension order i use is:
gd.so
imap.so
mhash.so
domxml.so
mysql.so
curl.so
( I tried removing domxml, mhash and curl and the problems
were still there ) ...
Also to throw in, I have OCI8 configured with Oracle 8.1.6
(as seen above) .. linked with pthreads and using Apache
1.3.20...
Any more info if needed can be provided.
