Looking in /usr/local/ppp.log I See: ppp[1538]: tun0: Phase: Clearing choked output queue when I try to ping I get back a message it is out of buffer space. I have brought the tun0, fxp0 interfaces down and back up with no positive results. I have tried to cu -l /dev/cuau0 on all OS's but of course I do not connect to the modem. I have totally re-configured the interfaces with no positive results. Different external modems did nothing to correct the problem. The only way to solve the problem is a shutdown and restart. It is such a pain, I have tried Freebsd OS versions 8.1 and 8.2 also PCBSD 8.1 and 8.2 on TPX4 Asus boards, X5DPA-TGM+ Super Micro, GA-V7KMLS and GA-7DPXDW-C - GIGABYTE boards. I have a stand alone system on all the time now attempting to fix this problem while other systems are on high speed connections. I need a periodic modem connection for my servers from home. On FreeBSD 2.2.8 and 4.11 your rock hard, die hard systems I never had this problem. I skipped 5.X and 6.X they seemed to not be good for servers in the server room. Version 7.3 is my current. Version 9 looks a ways off, so, I need a fix version 8. >How-To-Repeat: It just happens. Some times in 30 minutes.
