IP conflict?

Hello All,

Ok, the problem. A request for data 
made to a server stack by stacks via
a LAN will on occassion return empty.

Sometimes things work perfectly and
all eight stacks will receive the data. But
when at times one or two of the stacks
do not receive the requested data, the 
user must restart their stack, which
"solution" always works.

My  guess is that the incoming requests for
data may be overwhelming the server, and
creating a bottleneck of sorts. In which case,
what might be a solution?

If it helps, below are the relevant script 
portions from both the server and the host
stacks, in the order they are triggered.

As always, thank you in advance,

Nicolas Cueto
