In the RealtimeReaperError*.Log file, you can find several errors like :
02:03:18 Severity 1 - RPA15: Out of memory with error: 12 while trying to preallocate -1288490096 bytes for file in path: D:\CA\NFA\netflow\datafiles\ReaperArchive15\#########\00001\1440460800\
Look for empty locked *.rpr , *.cmp files in the Netflow\datafiles\reaperwork folder with timestamps older than the current day. These files can get orphaned and left behind if the Harvester machine runs out of virtual memory or if the files are locked by a third-party process such as an AV scan or backup.
Delete or move these old files out of the ReaperWork directory, free up disk space if it is running low, and restart the Harvester services.
