And there are many reasons and things that can cause this too,
unfortunately. Modem are imperfect things, running over imperfect
telephone networks... :)

Any particular brand of modem or chipset? What types of connection speeds
are these users getting (look at a "show mX" then find the sX port they
are connected to)? How are your lines provisioned? A User-Request means
that the user was either reset from the CLI (or Amber), or the PM received
a terminate request (which is how most PPP client stacks disconnect). Turn
on a "set debug 0x51" watch it for a problem user until they get
disconnected and see if anything goes across (from either side), then run
it through the PPP decoder on our web site.

You should be using 3.7.2c3 which is the latest modem code (well besides
a beta release).
