Error Occuring While Processing Data With DIAdem 8.1Excepti​on EAccessVio​lation in module ntdll.dll at 000111DE. Access violation at address 7C9111DE in module 'ntdll.dll​". Read address 37363430

Question

Hello,
We are having an issue running Diadem 8.1 on a new HP XW 9400 with Windows XP SP2. 3 errors have been occuring with frequent crashes, they are:
1) "1Exception EAccessViolation in module ntdll.dll at 000111DE. Access violation at address 7C9111DE in module 'ntdll.dll". Read address 37363430.
2) The instruction at "0x7c9111de" referenced memory at "0x352e302d". The memory could not be "read".
 3) ---Error---   DIAdem
Error in Autosequence - processing in line: 74 (IARV_VAR_GET)
Runtime Error while executing command "Iarv2Txt$ := FR(T9,L1)"
Error type: ACCESS VIOLATION
Error address: 000101DE
Module name:ntdll.dll
We are using the same scripts and version 8.1 on a variety of Dell desktop computers (W2K and XP SP2) without any issue, looking for suggestions as this affects no other software on the HP XW 9400 other than DIAdem. Appreciate any suggestions.

Christian,
I will answer your questions in the text below. Thanks for your help.
Hi swillh,
I also would like to help you.
Unfortunately, The reported access violation in the central Windows ntdll.dll is very unspecific.
May be the following questions will help you to provide me more info.
1. You mentioned that the aut's and - I think - also the accessed text file reside on a server.
Is there a stable network connection?
The server can sometimes be a little slow but the connection is good. This computer is using the same connection that the prior computer utilized without issue.
Are the files accessed by multiple clients simultaneously?
It is possible that more than one computer can be accessing the same file, but again, this has never been an issue. We are reading the files only, not writing to them.
The processing routines we are running have used for over 5 years without any issues until adding this computer.
Is the text file read by one client while another client is writing the same file?
No, files are "read only"
2. Have you already tested opening the file with the FileOpen command before calling FR?
Yes
Do you see any chance to convert the aut to a vbs file? This gives you more alternatives in accessing text files.
3. What do you mean with "processing ATD's with 30 or more channels of data"? Where is the relation between ATD files and data channels?
Processing Crash Dummy data with file sets low in channel count (15 channels) result in successful processing without any crashes or access errors.  When processing dummies with more than 20 channels we sometimes encounter these issues. The higher channel count may be the only common factor I can find in these faults.
