System configured with commit-archive via scp:
# show system config-management { commit-archive { location scp://user:[email protected]/data } commit-revisions 100 } ...
On upgrade to latest 1.4 rolling release (system previously normally ran 1.4-rolling-202105091233), the boot stops at Mounting VyOS config ... done. The router can be pinged and eventually logged into via SSH.
ps aux shows:
root 12460 75.6 1.8 182620 27384 ? Dl 08:23 0:02 python3 -c from vyos.remote import upload; upload("/tmp/config.boot.12456", "scp://user:[email protected]/data/config.boot-vyos-backup.20210517_082334", source=None)
It appears that VyOS tries to push latest config via SCP, but in the process uses 100% of one (v)CPU. System then fails to respond for a while, as the memory gets exhausted, until the message is output on the console as below.
