Re: Freshman hammering Clean Access






Thanks, Daniel!  Actually I THINK the problem was a bug that degrades the 
database over time.  We could either upgrade to 4.0.6, or "vacuum" the 
data base.  We chose the latter, and for now it seems to be holding 
steady!  (Fingers crossed)  Strange, though- we upgraded to 4.0.4 in Jan 
07, and it took it this long to degrade to the point of non-functioning!

Even if you hard coded the switch port settings at both ends, you may
still have issues if you are using Cisco switches.
Having both the card in the PC and the switch port set for auto
negotiate will work best in most cases. Otherwise, as another
contributor alluded to, you may be having ugly time outs and slowness
that is causing your issue. Have you done a packet dump at the CAS end
to see what is reaching it? Also check your vlan settings on each side
of the CAS to make sure you don't have a switch loop. I did that once
inadvertently and experienced exactly what you are seeing. 

Good luck.
