Χάθηκαν 3 μέρες από το syslog?

Διατηρώ ένα VPS με openvpn, torrents κλπ, με τον οποίο δεν είχα αλληλεπιδράσει για λίγες μέρες, σήμερα πήγα να συνδεθώ με ssh και άργησε αρκετή ώρα, μετά παρατήρησα ότι ότι στο /var/log/syslog.1
σταματάνε οι καταγραφές στις Aug 23 10:32:20 και αρχίζουν στις Aug 26 18:08:59, μάλλον τη στιγμή που συνδέθηκα σήμερα με ssh. Υπάρχουν κάτι σφάλματα στο τέλος της 23 Aug, που καταλαβαίνω ότι παραπέμπουν σε υπηρεσίες που απέτυχαν να αποκτήσουν πόρους? Παραθέτω το κομμάτι syslog με αποκομένες τις προφανές ευπαθές πληροφορίες :

Σε όλες τις καταγραφές φαίνεται να “πάγωσε” το λειτουργικό για 3 περίπου μέρες, μέχρι που προσπάθησα να συνδεθώ, επιβεβαιώνω από τις υπηρεσίες που παρέχει ότι δεν επικοινωνούσε για 3 ημέρες, αλλά το uptime δηλώνει κανονικά 16 μέρες. Θα μπορούσε κάποιος να διαμορφώσει θεωρία που να εξηγεί το γεγονός του παγώματος?
Ευχαριστώ

Δώσε λίγο παραπάνω στοιχεία…
Τι σόι vps είν δαύτο?
Τι distro τρέχεις? Ubuntu server ή κάποιο ubuntoειδές (ποιο)? Ποιον κέρνελ?
Το τρέχον setup το έχεις καιρό και έτρεχε ΟΚ ? Έκανες κάποια αλλαγή πρόσφατα και αν ναι τι?
Μετά το συμβάν αυτό έκανες reboot και το μηχάνημα δουλεύει ΟΚ χωρίς προβλήματα?

H παρακάτω ερώτηση μπορεί να είναι εντελώς χαζή (αν πχ έχεις έναν νοικιασμένο cloud vps από κάποιο μεγάλο μαγαζί, πχ hetzner): όλα εντάξει με τους δίσκους του συστήματος?

Ναι φυσικά, θεώρησα μήπως κάποιος αναγνωρίσει τα σχετικά μηνύματα στις καταγραφές.

Είναι από την υπηρεσία https://okeanos.grnet.gr/home/ με ακαδημαϊκό λογαριασμό πρέπει να έχει αναφερθεί ξανά εδώ στο φόρουμ.

Ubuntu Server 18.04.5 πυρήνα 4.15.0-112-generic

Το έχω από απρίλιο-μάιο, δεν εκτελεί τίποτα κρίσημο, περισσότερο για ακαδημαϊκό ενδιαφέρον τρέχω tor relay (οχι exit, δεν επιτρέπεται), και άλλα πειράματα.

Πριν 16 μέρες έκανα ενημερώσεις και επανεκκίνηση τελευταία φορά, δεν παρατήρησα τίποτα αξιοσημείωτο.

Ακόμα δεν έκανα reboot. Συγκεκριμένα δεν μπορούσα να συνδεθώ, ξεκίνησα κονσόλα από τη διαχείρισή του από την υπηρεσία okeanos, εκεί συνδέθηκε και αμέσως μετά μπόρεσα να συνδεθώ και με ssh. Δεν παρατήρησα τίποτα άλλο ύποπτο αλλά από παντού είναι λες και δεν υπήρξαν αυτές οι 3 μέρες στο σέρβερ σε καταγραφές, σαν να πάγωσε η κατάσταση του μέχρι τη στιγμή που προσπάθησα να συνδεθώ σήμερα το απόγευμα.

EDIT Από τη στιγμή που συνδέθηκα δουλεύει κανονικά.

Για παράδειγμα στο vnstat, βλέπετε λείπουν οι μέρες 24,25 αυγούστου.

Αυτό φαίνεται από τη σελίδα διαχείρισης του σέρβερ

Για δίσκους συστήματος, δεν γνωρίζω πως να βρω πληροφορίες, σε ανακοινώσεις δεν βρήκα τίποτα σχετικό για διακοπή υπηρεσιών ή συντήρηση. Αλλά δεν έχω ξαναδεί παρόμοιο περιστατικό. Προσδοκώ να είναι τίποτα bug-οειδές με το λογισμικό του σέρβερ ή να επικοινωνήσω με την υπηρεσία?
