One small point, there is one small bug in the error queues which is
that the element pushed into error queue doesn't have an updated value
of to_urec_ptr which is important to construct the hash key. This
will lead to undolauncher/worker think that the action for the same is
already processed and it removes the same from the hash table. I have
a fix for the same which I will share in next version of the patch
(which I am going to share in the next day or two).

I could see the problem, will fix in next version.
Thank you for reviewing and testing this.
