Why do I keep getting timeout errors in SQL?
This shows no deadlocks at the times of the problems, and long running queries all coincide with our timeout errors, but look to be a side effect, and not the cause. Queries that are very basic that typically return instantly end up taking 30, 60 or 120 seconds to run at times.
What is causing query timeouts in ADO.NET?
Normally the query executes in several milliseconds, but occasionally I get a period that lasts for several minutes where every attempt to execute this query takes 30 seconds and the ADO.Net client times out. I assume this is a locking problem on a particular table as other queries are not timing out.
Why does query keep time out when attempting?
Problem: I have a table in tabular data model using a SQL Query for a data source. The query in question requires about 3 minutes to regenerate. When I open Edit Table Properties for this data source the query times out and I get an error (see below): ” Failed to retrieve data from udvTrainJobReportsData.
What causes a 30 second timeout on a query?
About 10 minutes after the Lock:Escalation events stopped, I then got a series of timeouts on my query again, which all corresponded to a Lock:Cancel event on the same table. The 30 second timeout is a client side setting of ADO.Net. It seems that time out is caused by blocking with read and write operations on the same record.
Why are soql queries throwing limit exception before test?
SOQL queries limit hits before “Test.StartTest()”. We want to test a batch process and it needs to creates records for around 8 to 10 objects which has triggers. Because of that it is throwing limit exception before “Test.StartTest()”.

Why are my SQL server DBMS not working?
My experience with these issues (not on SQL Server though) is that overdone multi-tasking is often the cause of the problem. If there is similar/connected data/tables queried at (almost) the same time by many connections, the DBMS may have trouble keeping all the isolation at check.
