Ayrica httpd servisini restart yaptigimda tüm domainlerde bu uyari geliyor:

[Tue Jun 02 16:18:27 2009] [warn] Init: SSL server IP/port conflict:

Sorun nereden kaynaklaniyor olabilir, google olumlu cevap vermedi. Umarim sorun basittir.

Tesekkürler.

"segmentation fault" = korku + hüzün + çaresizlik

Öncelikle, eğer bu konuları az biliyorsan ilk yapman gereken şey, apache , ona bağlı tüm modüller, modüllerin çalıştırdığı tüm dış programlar (php gibi) ve bu programların tüm eklentilerini güncellemeyi deneyebilirsin.

Eğer konuya hakimsen, segmentation fault nerede ne zaman meydana geliyor bulup ona göre gerekli programı güncellemelisin veya kaldırmalısın.

Eğer bu genel bir sorun değilse (ki %99.99 değildir) sorunun kolayca uygulayabileceğin bir çözümü maalesef yok. Durum "segmentation fault"u meydana getiren programın hafızayı düzgün yönetememesi veya ona ulaşamaması veya zaten ulaşamayacağı bir hafıza bölümüne ulaşmaya çalışması. Yani tamamen yazılım ile alakalı (ayar veya başka bir şey değil).

Çoğu zaman modüller kötü yazıldığı için böyle hatalar oluşur, eğer yeni eklediğin herhangi bir apache modülü varsa onu kaldır ve kontrol et.

kurdugum bir tek xcache vardi, kaldirip denedim etkili olmali. "segmentation fault" hatasi error loga habire yazdi.. http.conf dosyasinda degisiklik yaptikdan sonra 5 dakikada bir error loga yaziyor. http.conf oynamasindan sonra daha iyi oldu gibi ancak her 5 dakikada bir tek tük errora yazmaya devam ediyor..

mod_php i kapatıp aynı hatayı alıp almadığını kontrol et...

Malesef sorun devam ediyor.
Tüm bilesenleri kaldirip,hatta tekrar kurdum. Sonuc ayni..

httpd.conf dosyasi icerisindeki bir mod dan olabilir mi.

yukaridaki modlar ne ise yaradigini bilmiyorum.

Apache versiyonu nedir?

mem_cache modülünü kaldırmayı deneyebilirsin.
