Unfortunately it looks like that the fix is quantative rather than qualitative - with 2.3.0 it is easier to expose the issue with lower amount of dimms, while for mentioned tag <8G configurations with 512M dimms have a very low chance to hit the corruption. I`ve moved test cycle to the 2G->16G memory update (31 DIMM in total) configuration and now always experiencing a crash during plug->migration cycle with running fio job inside. Anyway, commit which reduced the bug appearance ratio is still a target for me as it can shed some light to its nature.
