Problems with digital modem cards on AS5300

Hi

We have a large quantity of AS5300's for dialup user access.
Recently we have encountered a new problem which seems to have started out
of the blue:
We see the Digital Modem Cards getting stuck, so users cannot connect. When
the problem happens, we can see on 'show modem' that users cannot connect to
all the modems on a single modem card (we have 2 cards each...). We only see
modems in C mode (Connecting...), while on the other modem card there are
modems in * state. Also no modems are marked B (Bad).

We run IOS 12.0(7)T on the ASs. The modems are Mica's with 2.7.1.1 firmware
revision.

When we reload the RAS, the problem goes away for a few hours (even days)
but then comes back.
We first thought it to be a simple hardware problem, but we keep getting it
in different POPs and on too many devices...

Has anyone ever seen such a problem? Ideas?
