dropped connections after 120 secs or so

We are a small ISP running Portmaster 2E-30s with radius authentication.
We are running ComOS 3.3.2c1 on our Portmaster, and FreeBSD 2.1.5 on
our radius server. We are using USR Sportsters (28.8) of both the "new"
and "old" varieties. We have radius accounting enabled.

We have a lot of customers who complain that they frequently get
disconnected within the first couple of minutes of being
connected. If the connection lasts 5 minutes, it will last forever,
but frequently the customer will be disconnected several times
during the first 5 minutes. The problem doesn't seem tied to any
particular set of modems on my end.

Where should we look for problems? The fact that the customer can
eventually connect reliably suggests to me that the problem is on
my end, but I'm not sure if it's our modems or our portmaster or
our radius server that causes the problem?

Any suggestions?

Thanks much.
