FACT(s) (Environment):
Windows 2000
Progress 9.1x

CAUSE:
EXCEPTION_IN_PAGE_ERROR means:
"The thread tried to access a page that was not present, and the system was unable to load the page. For example, this exception might occur if a network connection is lost while running a program over the network, or local machine memory issues like paging."
This has been recognised as a problem with Windows 2000 when using (say) a Windows 2000 server with Terminal Server ( TS ).
The contents of an executable, EXE or DLL, is read on a need-to-execute basis. When the file in question is located on a remote share and Windows no longer can read it's contents (swap in as needed), then Windows will throw a exception C0000006 (IN_PAGE_ERROR).
The problem is in the Microsoft Network Redirector. It closes a file that is still in use, because it only uses one remote file control block (RFCB) for all users of a file. When the first user of a file logs out of this terminal session the redirector sends close file to the server. This happens even when other users have a reference to this RFCB.
This is documented in Microsoft article 272127 as was initially addressed in SP3.
FIX:
Apply latest Microsoft SP's to your Windows O/S.
