Hi there. I have two ASA5506Xs which have started rebooting daily. It appears to have started once I renewed their SSL certificates. However, everything SSL wise appears to be working fine. The two devices are connected by a network tunnel.
It's definitely a reboot, I have checked the uptimes for both devices and seen physically/had someone verify physically the device rebooting (status lights etc). I have attached the most recent crashinfo file for one of the devices. This device in particular is running ASA version 9.7(1)4.
The only things that looked concerning in the crashinfo.txt were these:
Reading from flash... !!!!!!!!!!!!WARNING: Enabling the logging ftp-bufferwrap feature could cause a depletion of all available memory under high syslog rates. Please adjust your buffered logging level appropriately *** Output from config line 463, "logging ftp-bufferwrap"
Are you using that command for a specific reason?
Also, we see the following:
A CPU hog that lasted more than 10 seconds was detected. In most cases this could have triggered a crash. Open a TAC case to diagnose this problem further
