The device hangs

Good afternoon! I have several AnywhereUSB / 14 in my company. Once a month, I observe that the device hangs and stops working and ssh, ping and https access.
Latest firmware (build 82002081_P awusb14 eos 2/02/2018 8: 27: 24a) (carried out a firmware update is here /). I thought that this would fix the problem, but the device continues to hang.

Additional information.
Boot Version: (release 82002082_B awusb14 bootloader 11/09/2009)
POST Version: (release 82001552_A generic_travis hwdiag 11/09/2009)

The clients have the latest 3.95 drivers installed. It is very sad that because of the fact that there are 14 keys in it, the work of a large number of people rises. You can tell what can be done, and where I can look at the device logs, at least to understand the reason to dig, I did not find the right item in the web interface. I will be grateful for any help.

why is there no such command on my DIGI?
