Hello,
I am using the Indy UDP server component in an application, and am 
experiencing quite a few missed packets in circumstances where the 
UDPRead method isn't called quickly enough after a packet arrives. For 
example, if I pause the program briefly in the debugger packets are 
invariably lost. This also happens in normal operation if there is any 
delay in responding to incoming data. Is this normal behavior for the 
UDP server? Is data lost when the Read method is not called before more 
data arrives? How can the problem be resolved, or can it be?

Thanks
Dave
