We had (probably) the same problem a while ago, see #8502

[pSub]

[vcunat]

I don't know if we can do something with such issues.

[pSub]

@rbvermaa suggested to create an issue and wanted to forward the information to amazon.

[jagajaga]

ping

[pSub]

FWIW I haven't experience this issue since then.

[vcunat]
