[PVE-User] Recurring crashes after cluster upgrade from 5 to 6

[Eneko Lacunza]

Hi Alexandre,

Sorry for the delay getting back, I missed your reply.

I see the following versions:

corosync: 3.0.2-pve2
libknet1: 1.12-pve1

So no :(
Was this (important?) fix announced somehow?

Anyway, will upgrade the cluster ASAP, thanks a lot for the hint!!

Regards
Eneko
