These are my results for the manual send calls:

Seems like some problem with udevd handeling the sequence numbers..

This seems to be the problem with udevd queueing the event forever.

I resolved this issue by increasing the size of my tmpfs mounted /dev. The db grew too big for the 100k size limit.
