Using the new Transfer Tool in WHM / you may encounter 1 or more accounts that are stalled and the transfer tool in hung in Pending Status or if you try to pause / hung in pausing status.

You need to know the pid of all the current transfers (usually up to 5), in my case, I had to very big accounts being transfered (40 and 70 GBs each).

Some steps
1) Run the /usr/local/cpanel/bin/view_transfer 1054056copya20140XXXXXX
2) Find the transfers or restores still running.
3) Do kill -9 PID (where PID is the pid of all the processes still running)

You should see the status update / in the transfer tool gui as you kill off the process's / Confirmed in 11.48.2 Builds
