Starting this year our desktop clients slowly stopped working out of the blue. First they had problems synchronizing. Then they started crashing. After multiple reinstalls I am stuck with:
100% 1 core cpu usage through client
it starts synchronizing, stops after 2-3 seconds and freezes
AppImage does not freeze.
AppImage stops working after 1-2s too.
I dug further and there is a huge packet loss in the system.
Client <> Google 0.5%
Client <> Nextcloud 20-40%
Above around 20% packet loss all the clients stop working. Its not clear why but the main question now is the whole packet loss situation.
Package loss occurs between our router and the Proxmox PVE, new cables reduced it from 20-40% to 8-22%. NICs and the main glass fiber router have been replaced too, but the effect seems to be near placebo. Do you guys have experience with such a situation?
