Hello,
We are facing a huge memory leak with unattended-upgrade binary. It appears that in around 20s, 2.9Go (80%) of RAM is consumed by the process making the system unresponsive (even a basic 'ps' command remains stuck).
Note: the logs were captured on a system configured in French. I manually translated some words below, which could explain it is not exactly what you would have on an english based system.

The swap was voluntarily disabled, but anyway I do not expect such a process to consume up to 3Go of RAM in nominal operation.

- screenshot of syslog (from a distinct run) showing that unattended-upgr went out of memory and was killed by OOM. You can also see that the run occured as part of the apt-daily service. |
