the server code is in the provided images

heres the client code:

instructions: Write a distributed application that calculates the sum of a huge data set.

for the most part this code functions but there are some issues:

$1.$ the server terminates by itself when it should not be doing that

$2.$ after the workers are finished, the final sum should reset to $0,$ but it doesnt.

$3.$ ive tried to make it work to where it can calculate the sum regardless of whether one worker is working or all of the workers are working with interesting problems as a result.

these are the problems I have been dealing with and I am rather lost on what to do next
