Hello Alexey,

thanks for your hints.
We have found 2 issues over the weekend.

1) A loose contact on the SATA Backplane of the MDS. Nasty one this was.
2) Some sporadic high percentage of package loss for a few seconds/minutes.

I think i need to fix these issues first before getting on.

Regards
Heiko
