CAT9K 17.6.4 // python3 cli-API: OSError: [Errno 28] No space left on

Maybe someone ran into the same problem?

- After every run, more and more diskspace is shown as used.
- After 100% diskspace usage is reached, the script fails, no diskspace is released anymore, the python3 scripts can no longer be executed and the guest shell must be destroyed and reactivated to get this working again.

# python3 script used to reproduce issue

guestshell run python3
import cli
for s in range (1,10000):
print (s)
x=cli.cli("show version")

# sh platform software mount | i /dev/loop11 showing diskspace
