At one of our client, When we go into the debugger system is not showing any active sessions even-though there are many users (at least more than 50) are logged in the NAV 2013.
I started looking into this issue and found that the issue is in "Session Event" table. in this table, when user get logged in the entry get inserted as Logon but immidiately in some seconds other entry for close and Logoff get inserted with comment of "Force closed by server" but the user is still working on the system and hence that user is not getting available in Active session and debugger.
This issue is now pain for us because we are not able to debug the session in case where there is a problem in transaction and we need to find out the issue.
Please help us in this matter.
