In addition, the active process_stdout.log and process_stderr.log log files will show zero bytes in size. These files can be viewed with this command:įirepower #> lsof | grep deleted | grep process_std

For systems that operate (or that have previously operated) with affected Firepower software versions 7.0.x and 7.1.x, the process_stdout.log and process_stderr.log log files continue to log events and consume excessive disk space after they are flagged for deletion and become hidden files.

The Secure Firewall will indicate "High unmanaged disk usage on /ngfw" and the Secure FMC will indicate "High unmanaged disk usage on /Volume". Health alerts will be indicated when the disk consumption becomes excessive. There are two symptoms for the issue described in this field notice.įor both cases, if the log files consume all available space on the system disk drive the user might be unable to log into the device and a system reload might be required to regain login access.

This condition might result in the consumption of most or all of the available disk space on the system. The log file management process maintains recent log files while older log files are flagged for deletion in order to conserve disk space.įor some versions of Firepower software, the log file rotation pointers for the process_stdout.log and process_stderr.log log files are not reset correctly, which causes log files to consume additional disk space and prevent older hidden log files from being automatically deleted. The Firepower software uses a log file rotation ( logrotate) process to manage log files that are stored on the disk of the Cisco Secure Firewall and Cisco Secure FMC. Some versions of Firepower software might cause log files to consume excessive disk space on the Cisco Secure Firewall and Cisco Secure Firewall Management Center (FMC).
