Bir süre sunucu tarafı izlemesi çalıştırdım ve genişletilmiş olayları kullandığım gibi aynı boş düğümleri bir izleme dosyasında alıyorum.
Bu engellenen işlem raporu, Dynamics AX çalıştıran başka bir sunucuda sunucu tarafı izlemesi kullanılarak yakalandı, bu nedenle bu sunucuya veya yapıya özgü değil.

Bu raporlar için bir açıklaması olan var mı? Sorguyu engelleyen nedir?
Kilitler çok geçtikten sonra raporlara bakarsam ne olduğunu öğrenmenin bir yolu var mı?
Eklenmesi faydalı olabilecek bir şey, bu sorguların sp_cursorprepare
vesp_cursorexecute
Şimdiye kadar onu yeniden üretemedim, rastgele ama çok sık oluyor gibi görünüyor.
Hepsi Dynamics AX ile ilgili birkaç durumda (farklı yapılarda) ve birkaç tablo / sorguda gerçekleşir.
O sırada arka planda meydana gelen herhangi bir dizin veya başka veritabanı bakım işi yoktur.
Cevapta srutzky tarafından verilen kodu kullanarak, bu engellenen süreç raporuyla ilgili bir miktar kayıt tutmayı başardım:

Diğer araştırmalar, rapordan hemen önce ve sonra boş bir engelleme işlemine sahip olduğumu ve aynı işlem için engelleme işlemi düğümlerine sahip olan raporları bulunduğunu gösteriyor:

Srutzky tarafından sağlanan yeni senaryo kullanılarak yeni veriler toplanmıştır. Maksimum direk uzunluğu nedeniyle github'a gönderilir .
Başlangıçta gönderilen veriler her ikisinde de oturum kimliğine sahip olmadığından, bazı yeni veriler tekrar github'da yayınlandı .
