Hello Steven and Whit,</div>

Over this weekend, I noticed that the data log file was automatically switched to the secondary directory path configured on the FTView data log system.<br>

<div class="x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0); background-color:rgb(255,255,255)">
I checked this issue and found that the primary path become unavailable because of the Microsoft Access database file size limitation (only allows database files of 2 GB size) and since the current data file already reached this size is not allowing more data
be archived in it.</div>
<div class="x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0); background-color:rgb(255,255,255)">
Data is still being archived on the secondary path with no issues, but to avoid warnings about failing to reconnect automatically to the database file on the primary path, we have to initiate another data base file or at least subtract/reduce data from the
current one.</div>

The data recorded from January 17, 2023 would be still available on the Access file if it needs to be referred.<br>
