BUG Restarting electrumx will cause a stuck

[Jamiejoin]

I installed the electrumx of the latest master branch. Thank you very much for the memory leak problem that has been solved after testing, but I now encounter a new problem. I try to kill the electrumx service. When I start it again, it will get stuck in a position and cannot continue. , And it will be stuck to the position of the log below after restarting many times

How much did you wait?

it might take several minutes to process that many blocks.
