I've seen this happen with PPPoX connections when either the ISP makes a
config change that causes the BRAS to disconnect the PPP session and for
whatever reason the CPE doesn't receive the disconnect message so the
PPP session remains active and thus never re-negotiates a new session.
I've also seen similar issues on connections that have a poor local loop
(packet loss due to link errors), PPPoE over wireless last mile, etc.
