Production database log file is getting increased rapidly.

Hi Guys,

I am facing issue on production environment available onazure(VM). The database server is (SQL Server 2016 EE on Windows Server 2012R2 DC) inHA-AlwaysOn& on the same environment, one database log file is getting increased very rapidly. Approx. 10+GB per day growth in log file. Previously, the LDF file size was 44 GB & now it is approx. 400 GB. MDF file size is 56 GB.

Tried to check the latency between both the nodes & is<=1ms.

Required your help to identify the reason behind this unpredictable behavior of SQL Server.

Thanks

Dhanush
