ISDN AS5300

Recently I have experienced some problems with logins on my AS5300. Clients log in fine for a few days after a reboot. After a few days clients can not log in and I am noticing a peculiar line in my debug PPP negotiate that looks like this;

*Jan 3 19:32:00.891: Se0:6 PPP: Pending ncpQ size is 11. The negotiation is timing out as well.

Then the line terminates. Does anyone have a clue on this one?

NCP (Network Control Protocol) is the third and final phase of PPP negotiation. Sometimes this can indicate that the pool of IP addresses is exhausted and that there are X (in this case 11) requests for addresses queued up. Most times, though, it's an IOS coding error, and an upgrade would be in order. Without more details, a definitive answer is hard to give.
