Data corruption can happen on a file located on a server when using testapplications that do the following:
Test Application One:
Service running under a user account that has no access to the file server directory where the file is located.
Try to obtain file attributes of a file located on the file server in an infinite loop.
Test Application Two:
Application that has rights to the file in the directory that Test Application One is attempting to use.
Open/creates file, writes 20 bytes of data, closes file, wait 500 ms, open file, read data, close file, compare Data, wait 500 ms, and start the loop again.
This application will soon detect data corruption in application data filesduring the compare operation of the loop.
A zero length condition in the cache manager was not accounted for andcaused the data to be flushed.
