[PVE-User] PVE 3.2 / Packet loss on Bridge-Interfaces

Hi,

we have a tinc-bridge on our hosts which is used by multiple guests on multiple Servers. On one host we have some problems. Pinging other hosts shows a stable connection, but only if the ping-target is located on another pve-host. Pinging a machine on the same host (connected via the tinc-bridge) results in massive packet loss.

As you can see from the ping-log below, every ~90 seconds there is a ~45 second timeout. This is of course not acceptable.
I can't say at this point if this is even a Proxmox or Tinc issue. But I hope you guys can point me in the right direction.

Any hints how to resolve or debug this issue?

Here's the mentioned Ping-Log
