Somebody on this news group have an idea about where is the problem ?

With CVSUP we localised when the source have stop to work.
it's: 1997.06.16.13.26.26
1997 june 16, 13h26 26s.

Maybe what you say is true. But we have an other cue.
In the main() func. of the name.c., if we remove the two close(), it work fine.

We cannot try somthing because our two clycloms 16 are in a big production serve
r
.
And we have not enough $ for buy an other just for make some tests...
If I am able to put a hand on an other Cyclom 16, I will be OK to debug it.
But I dont know where I will find it in Quebec City, Canada.
( I program better in C then I talk english... ;-) )
Give me some news if you can find a trace of the problem with more precision.
If I do this modification, it work... But I dont know why !
