Merhabalar 2 gün önce sabah saatlerinde sitemi kontrol ettiğimde ''veritabanı bağlantısı kurulurken hata oluştu'' ekranı gelmekteydi.

Error logdan kontrol ettiğimde sürekli olarak tekrarlayan aşağıdaki gibi hatalar fark ettim. Hem kendim hem de hosting firması çözüm bulmaya çalışsakta çözemediğimiz için güncel yedekle şimdilik problemi giderdik.

Ancak sitede herhangi bir işlem yapmadan bir anda ortaya çıkan bu hataların tam olarak neden kaynaklandığını ve tekrarlamaması için ne yapılmalı ya da nasıl bir önlem alınmalı danışmak istedim.
