Re: (ASCEND) Urgent TNT problem

I am playing this same game here with p24. It started when I added a 4th
nailed T1 on the TNT. I took it off and put it on another TNT and the
problem went away. Its ticket #195174. Basically it would do one of two
things. Every night one of the nailed connections would quit being routed,
but still be connected. I could kill the session it would come back fine.
The other thing which happened once or twice a week is the box would drop
all the nailed connections completely, this called for a reboot.
