It seems likely that someone could perform a denial of service attack by
requesting telnet sessions programmatically which is why I think they have
the limit.  I have mine set at 350 up from 200.

QAutoVRT was set at 100. Reset to 500 and seems to have fixed it.
 
Setting has worked ok for a long time. Can alot be created all at once by
something?
 
Do virtual devices go away automatically after they are created?
 
Thank you for your excellent assistance.

Hi Darran,

        I may be wrong, but we had a similar problem which I traced to the
System Value :
System value . . . . . :   QAUTOVRT                     
Description  . . . . . :   Autoconfigure virtual devices

We had too few allowed which prevented anyone from signing on to a virtual
terminal once all were in use.  After upping the number a little the problem
went away.  I think it is a good idea to limit this just need to provide
enough...  Hth
