Subject: | NSA/TSI/C1 - Software problem |
DataStreams: | nsatsimovieC1.a1 |
Description: | When the TSI computer was upgraded to a Windows 7 virtual machine, the scheduled task to stop the software each day was not configured correctly. Image processing became back-logged requiring manual intervention and use of the batch processing feature. This resulted in missing cldmask files and out-of-sequence movie files. The scheduled task was corrected. |
