sql error on application log

  • Sorry about the wrong information. Default instance is running on port 1433 and named instance is running on dynamic port.

  • The connection of the The App was killed !

    You should start by verifying what was going on on the server at that time!

  • The message saying the connection was forcefully closed usually means that either the connection was explicitly killed by someone, or the query hit a high severity error and was disconnected.

    Both of those will be reflected in the SQL error log. Check there.

  • How can i verify what is going on the server? I checked the error log, there is nothing there.

    Should I turn on the profiler? What event should i capture in profiler?

  • I set the profiler to audit fail login, login, sql:batchstarting, sql:batchcompleted.

    Do i need to collect some other events?

  • The error events. Exception, errorlog, user error message, attention. There may be some others worth checking.

    How long are you planning running profiler for?

  • I have set the profiler for error event.

    I am planning to run profiler until erorr occurs again and application stops sending updates. Is that OK?

  • what event i have to start to collect information regarding network issues?

    I hope this is not sql server isssues or port issue.
