Hello,
We are currently having a problem with our Alpha server crashing from time to time. It does not happen every day, but I would say 1 to 2 times per week. We are running Alpha5v7 web app server, which works fine. The crash report below is what we get every time the system crashes. I did some looking around and found some information that this may be related to a print driver, but we are not sure. has anyone seen this problem before, or have an idea of what driver could be causing the issue? Thanks in advance for your help.

SESSION_HAS_VALID_VIEWS_ON_EXIT (ba)
Caused by a session driver not unmapping its mapped views prior to a
session unload. This indicates a bug in win32k.sys, atmfd.dll,
rdpdd.dll or a video driver.

Arg4: 0000001f, size of this session's mapped views table.
