ASA SSH sessions stuck in sh resource usage.

[algreg]

Hello,

We have Firepower 4120 chassis with ASA image

Cisco Adaptive Security Appliance Software Version 9.18(4)40 

SSP Operating System Version 2.12(1.72)

Device Manager Version 7.20(1)

Compiled on Tue 27-Aug-24 07:55 GMT by builders

System image file is "disk0:/fxos-lfbff-k8.2.12.1.72.SPA"

Config file at boot was "startup-config"

Periodically on our ASA "ssh server resource" limit is full and its not possible to ssh to the device anymore. Show ssh sessions shows that only 1 ssh session exist. It seems that some sessions were not terminated and stucked in the system. Only reload helps to clear sessions.

Does anyone know what can be the issue or how it can be cleared without reloading the appliance?
