Dear colleagues,
We have an issue with packet loss between Proxmox host and gateway/outside. It's around 30% and it doesn't always happen at the same time.
Ping between VM's and Proxmox IP is without packet loss. Ping between Proxmox host and gateway is around 30% loss (same from outside).
We tried:
1) Replace gateway router (also with network cables)
2) Change physical network card of Proxmox server to USB external network card.
Both with no change to the issue, so it seems HW is okay.
Dmesg -T shows no problem (only messages about the one switch between internal and external network card). No change in network settings before it started happening. No backups running in the time when the issue started. No relevant error in syslog.
When we restart the whole physical server, than it's without issue for few days, but than it starts again. Can't any proxmox buffer be full or something after few days (we are running web/mail servers)?
Could you please advice some other way how to investigate this?
Thank you in advance.
