Merhabalar,
Dün akşamdan beri sunucuda problem çıktı.
Problem şu mariadb sorguları ramda cacheliyor. belli bir yerden sonra cache 0 sıfırlıyor o esnadaki bütün bağlantılar
"An exception occurred in driver: SQLSTATE[HY000] [2002] Connection refused" hatası alıyor.

örnegin 28gb cacahe de tuttu bir anda 637 mb ya düşüyor cache ve bu sürekli gebe bir döngü olarak devam ediyor.

verdiği hata:
