No - they're just using a lot of transactions. Login and logout match
your comparative data below. Autocommit mode would easily account for
the higher number of transactions.

It rather sounds like "disk full", but I believe you're correct:

http://technet.microsoft.com/en-us/library/cc978735.aspx

User Action:
Do one of the following, then retry the command: (1) reduce the number
of running programs; (2) remove unwanted files from the disk the
paging file is on and restart the system; (3) check the paging file
disk for an I/O error; or (4) install additional memory in your
system.

As for the causes, I don't have a clue.
