SYSTEM_SERVICE_EXCEPTION (3b)
An exception happened while executing a system service routine.
Arguments:
Arg1: 00000000c0000005, Exception code that caused the BugCheck.
Arg2: fffff8067aaad398, Address of the instruction which caused the BugCheck.
Arg3: ffffe40f30cd68b0, Address of the context record for the exception that caused the BugCheck.
Arg4: 0000000000000000, zero.

Çok basit bir şekilde, sistem çöküyor çünkü bir bellek erişim ihlali oluyor. Bellek erişim ihlalleri bir sistem için normal davranışlar değildir. Özellikle buna kernel seviyede çalışan 3.taraf bir sürücü sebep oluyorsa daha büyük sıkıntıdır.

Sorunun sebebi Vanguard. Basitçe anlatıyorum neden bu soruna sebep olduğunu, bu yüzden Stack'leri incelemeye devam et.

Başka bir süreçte (yani "foreign process") tüm kullanılabilir adres alanını ayırmaya çalıştığınızda, virtualallocex (dosyada bulunmaz.) İşlevi, kilitlenmeye neden olabilir? Kilitlenme, senin dökümünde gösterildiği üzere, adres alanında uygun boş bitleri bulmaya çalışan rtlfindclearbitsex adlı bir işlevde gerçekleşiyor.

Tek tek açıklamak gerekirse:

1. adres alanı (address range) : Bellek ayırmak istediğinizde, işletim sistemi size mevcut bellekten bir alan tahsis eder. "tüm kullanılabilir adres alanı" ise bu süreçteki tüm boş belleği kapsayan alanı ifade eder basitçe anlatmak gerekirse.
2. rtlfindclearbitsex: Bellek ayırma işlemi sırasında boş (yani tahsis edilmemiş) bellek bitlerini bulmaya çalışan bir Windows işlevidir.

Eğer tüm adres alanını rezerve etmeye çalışıyorsa, rtlfindclearbitsex yeterli boş alan bulmakta zorlanır çünkü zaten tamamı rezerve edilmeye çalışıldığı için "boş bit" yoktur. Bu durumda, virtualallocex bu işlevin yanıt vermesini bekler ve işlev bir sonuca ulaşamayınca "kilitlenmiş" gibi görünür, yani yanıt veremez duruma gelir. Sürekli aynı işlevi döndürür durur.

Bu tip bir durum genellikle bellek yönetimi veya düşük seviye bellek ayırma işlemleriyle uğraşırken ortaya çıkıyor ve aynı şekilde bu soruna sebep olan aslında bu takılmaya neden olan da Vanguard. Yukarıda anlattığım şey tamamen kodlama ile alakalı bir hata.

Yani, bu durumda süreç sonlandırılamıyor, ya Valorant ya da Vanguard kapatılamıyor ve Windows bu sürecin kapanmak üzere olduğunu düşünüyor. Bu yüzden, sistem yeniden başlatılsa bile süreç kapatılmıyor. Sorunu çözmek için cihazın tamamen kapanıp tekrar açılması (Full Power cycle) gerekiyor.

Bu sorun, sürecin işletim sistemi tarafından “kapanıyor” olarak algılandığı bir durumda kalmasına yol açıyor. Bu durumda, süreç tamamen kilitlenmiş durumda olduğundan, normal yollarla kapatma veya yeniden başlatma işe yaramıyor.

Bununla alakalı ve tamamen aynı kilitlenmeye sebep olabilecek bir kod örneği.

---------------------------------------------------------------

Vanguard'ın bu tip bir hataya sebep olması da genel. Son 1 ayda Vanguard'ın ya kod entegresinde Windows 11 ile sorun yaşanıyor ya da bu arkadaşlar kodlamayı bilmiyorlar. İlki olduğunu düşünüyoruz şimdilik.

Eğer sık yaşamıyorsan bu sorunun Vanguard'dan dolayı ortaya çıktığını bil ve bilgisayarınla alakalı bir sorun olduğunu düşünme. Sık yaşıyorsan da bellek bütünlüğünü ayarını kapatmayı deneyebilirsin. Bu da kesin bir çözümdür diyebilir miyiz?.. Bilmiyorum. İşe yaradığı oluyor.
