Cleanup in TempDb T% tables possible in Dynamics AX 2012 R3?

Hi

We have a lot of tables in TempDB - top 10:

NAME Count
TaxWithholdTrans 64959
RetailSalesTable 2853
TmpInventSalesOverviewLines 1674
TmpInventSalesOverviewSite 1674
TmpDataAreaRecIdFilter 1231
MyRoles 643
SDSPurchLineTmp 315
WHSLoadLine 290
TmpWMSPrintLabelLine 259
TmpWMSPrintLabelTable 251

I would like to DROP these tables, every night (older than 24 hours), but is it safe? Our Terminal Servers is restarted every night aka "clean-cut".

100 DROP TABLE takes about 3-5 seconds.

WHY:

Our Stop-Service *aos6* can sometimes take A LONG time (hours) - and I then just "kill AX32Serv.exe" - not pretty :-(

We will have minimal down-time during AX delivery (STAGE -> PRODUCTION).

Many of these tables have 0 rows, example: TaxWithholdTrans / 1816 - this may be due to disabling and "Module" in AX. But why do AX not cleanup nicely it self...

If deleting, then users can get errors like:

[Microsoft][SQL Server Native Client 11.0][SQL Server]Invalid object name 'tempdb.DBO.t112850_FBBD0BA9987D477783A6456038688C66'.

[Microsoft][SQL Server Native Client 11.0][SQL Server]Cannot find the object "t112850_FBBD0BA9987D477783A6456038688C66" because it does not exist or you do not have permissions.

[Microsoft][SQL Server Native Client 11.0][SQL Server]Cannot drop the table 'tempdb.DBO.t112850_FBBD0BA9987D477783A6456038688C66', because it does not exist or you do not have permission.

( this error comes EVEN if the users has been signout, and is not on the "online users" list ... so AX must keep it in the cache files also ?? )
