FastIO errors

FastIO errors

Post by Carl Ban » Thu, 04 Mar 2004 13:21:26

We have a VFP 5 application running on a Windows 2003 Server. The users
access the app via Citrix Metaframe XP.
Using the filemon.exe (file monitor) utility, I see many entries by my
application that look like this:

1 2:44:25 PM appname.exe:6556 FASTIO_CHECK_IF_POSSIBLE \\IP
Address\Directory\tablename.dbf FAILURE Read: Offset: 24120 Length: 636


2 2:44:25 PM appname.exe:6556 FASTIO_READ \\IP
Address\Directory\tablename.dbf FAILURE Offset: 24120 Length: 636

There are also many "IRP_MJ_READ" processes, but they all end in "Success".
All of the FASTIO processes fail.

Does anyone know what FASTIO is and why it would be failing on each attempt?

Hi Carl:

From what I can tell, FastIO is a type of file write used in Windows.
Since I do not support Windows, you might want to cross post this issue to
a Windows 2003 newsgroup.

The first thing I would try is use the Windows RDP client instead of the
Citrix client to see if that is causing the problem. If it works under our
RDP client, then I would contact Citrix. If it still fails under the RDP
client, I would post the question to the Windows newsgroup.

I hope this helps.
