Yes, the bug described in CSCwe21037 is primarily cosmetic in nature. The main intention of this bug is to change the way the health monitor tracks Snort memory usage. You can safely ignore the Snort utilization value reported by the health monitor as it doesn't accurately represent the actual memory usage.
As for the fixed versions, this bug will be addressed in the upcoming Firepower versions 7.0.6, 7.2.5, and 7.4.0. I recommend using the "My notifications" option from the Cisco Software download page to receive notifications about these upcoming Firepower versions.
To find the top.log file, you can access it by connecting to the Firepower Management Center (FMC) or the Firepower Threat Defense (FTD) device via SSH. Once connected, you can navigate to the appropriate directory and view the top.log file. The exact location may vary depending on your specific setup, but it is typically found in /var/log/ or /var/log/snort/.
If you need further assistance, please don't hesitate to reach out.
