"what does that mean?"
Generally it means a FIFO queue has overflowed.
"is it carrier issue or my shapper issue"
As the issue is usually caused by insufficient bandwidth, cannot say it's actually an issue of either.
I'll also note, the percentage of drops is such a tiny percentage, it's very unlikely this is an issue, especially as all the drops are in the class-default class which also is normally used for best effort.
