SysDictCoder: Fix for long AOS startup time

==============

When you’re starting an AOS you may notice it takes a very long time before the service gets the status Started. A possible cause is left-over data in the SysClientSessions table. When starting up, the AOS seems to check if the client is still around somewhere for each record.

I have noticed that not it’s not always cleaned up properly after an AOS is shut down. If an AOS is acting up and needs to be restarted anyway I check the table on SQL Server and delete the client records before restarting the service.

Don’t just do this if multiple AOSes are set up for the same application. All instances should be shut down before cleaning up data like this.

Unfortunately I haven’t yet figured out how records get stuck in that table after a graceful shutdown in the first place. Of course, if it crashes the sessions won’t be erased either.
