Comment 8 for bug 1555938

Dear zhangguoqing,

For now,"hitting scheduler always" will solve this specific issue only.

As pointed by LisaLi, there are some other operations as welll which will still need seperate fix.

So, I will be discussing this with our smart(cinder) guys and will be keeping this topic as cinder meeting point in next week.
There could be some better way to fix all issues in one go than hitting scheduler always.

So, lets discuss different fix perspectives in meeting on 30th of March, if possible.
