From time to time I'm getting messages in /var/log/messages like this: Jul 27 12:18:47 linux kernel: isdn_tx_timeout dev ippp0 dialstate 0
Sometimes 2 or 3 times in a row, 15 secs between it. As far as I can see, the connection with ISP is made. After these messages, ipppd is talking about MPPP negotiation, and connection is made and ready for use. In the meantime however, browsers and mailclients are timed out, so users start to complain. Is there anything I can do on my side, or do I have to complain at my ISP?
