Description
In rare cases of virtualized Linux environments, reading network counters from /proc/net/dev can return incomplete or unexpected data. As a consequence the database may crash and automatically restart).
Workaround
No reliable database-level workaround exists other than upgrading to a fixed version.
The probability of this issue can be reduced by keeping VM host network interface configuration stable during db runtime and avoiding host/kernel changes that may affect /proc behavior.
Fix
The network statistics parsing was hardened to handle malformed or partial /proc/net/dev input safely.
