I have recently found that my UML290 is chewing up data at around 1:00AM in chunks up to 500MB at a time. In the last week almost 2.5GB I have the session logs turned on on my Verizon Access Manager and none of it shows up? I have on session that started on 4-2-12 at around 9:30AM that has some how logged 1180+ hours roughly 49 days(not sure how that works) but still only like 150MB of data.
Anyone else having this kind of problem lately?
A recommendation check your software and find out which is one is trying to do a software update. I heard a similar case where an antivirus program was trying to update and the file was like 650 megs but during the update it would stall around 500 mb, so then the next night it would try again starting all over from 0,
You can also try checking to see if you have spyware, malware, or any Trojans that would be using that data on your machine.
