Hello
We are using SQL server 2017
Microsoft SQL Server 2017 (RTM-CU15) (KB4498951) - 14.0.3162.1 (X64) May 15 2019 19:14:30 Copyright (C) 2017 Microsoft Corporation Standard Edition (64-bit) on Windows Server 2016 Standard 10.0 <X64> (Build 14393: )
On IOs Windows server 2016 - 64 bit - dual processor @ 2.4 GHz - 64 GB RAM
Currently from task manager we have Memory used 93 % out of which 51 GB used by SQL.
C drive has 4.99GB free out of 49.99 GB.
SQL server memory options has values 0 as minimum and 2147483647 MB as maximum.
Whenever we try to do update on a certain table that has around 550,000 records and 1 GB size
, it takes several minutes for simple update to be executed and causes the whole sql to become busy and we start getting timeout expired on webpages in our website.
This table is used by several views and queries running on website.We did rebuild all indexes over this table and views using it since fragmentation percentage was high, but it didn't solve the problem.
It is the main source of info for our website.
What might be the reason of such behavior ?
