The glitch happens when I change desk-tops in KDE during a down-load. I get anywhere from 1 to 15 silo overflows each time I switch. I have tried other loads on processors such as pkg_add, play MP3, daily cron jobs and have no problem. I believe the problem is with the system and the way handles interrupts with dual processors. I do not have the problem when running with a single processor. I have tried increasing the receive buffer size from 16 to 64k with no effect. I have decreased the baud rate to the modem which does decrease the number of overflows but does not eliminate them. Any ideas or suggestions?
