try to disable some modules you do not use for cacti for example.
then try to enable some modules one at the time to see which  is faulty.

Also try to shuffle with the order in which they load.
I had the same with zabbix, and finally found an order in which my maps 
did not crash the server any more.

This is the order in my /usr/local/etc/php/extensions.ini

extension=zlib.so
extension=mysql.so
extension=gettext.so
extension=xml.so
extension=gd.so
extension=ctype.so
extension=session.so
extension=iconv.so
extension=pdo.so
extension=pdo_pgsql.so
extension=pgsql.so
extension=apc.so
extension=pdf.so
extension=bcmath.so
extension=bz2.so
extension=curl.so
extension=dom.so
extension=mbstring.so
extension=mysqli.so
extension=pdo_sqlite.so
extension=sqlite.so
extension=sqlite3.so
extension=json.so
extension=tokenizer.so
extension=filter.so
extension=hash.so
extension=posix.so
extension=simplexml.so
extension=xmlreader.so
extension=xmlwriter.so
extension=ldap.so
extension=mcrypt.so
extension=openssl.so
extension=snmp.so
extension=sockets.so
extension=zip.so

I do not have all the extensions you have, but maybe this helps you.
