I ran my Igate using a KPC-3+ in KISS mode.  I had to reset it every few
*days* because of this issue.  The software driving the TNC was irrelevant.
Saw the delays with Xastir and javAPRSSrvr driving the TNC directly.  
Replacing the KPC-3+ with a Tracker2 ended the issue once and for all.

I had 9.x firmware in my KPC-3+.

Someone here (or possibly on one of the Yahoo groups related to APRS) posted 
that they had been trying to get Kantronics to recognize and address the 
problem, but AFAIK they have not done so, and have claimed that they are 
unable to reproduce it.
