In some unknown circumstances multiple instances of journalctl for the the same LXC are run, over prolonged periods of time.

E.g., a ps faux | grep journalctl inside one of the containers will show:

root       21717  0.0  0.8 251392 17024 ?        S    Dec15   0:00 journalctl --lines 0 --follow --output json
root        6153  0.0  0.8 256340 18560 ?        S    Dec12   0:00 journalctl --lines 0 --follow --output json
root         317  0.0  0.8 257608 17152 ?        S    Dec10   0:00 journalctl --lines 0 --follow --output json

Those are killed if pve2otelcol is restarted; some logs seem, in fact, to be duplicated (to be validated).

We must identify the possible source of the problem.
