I wish this help you According to forkJoin documentation, it will wait for all of them to complete, and it maintains the order in which you lined up the requests, for the observables too.

With these it helps As detailed in the comments of the MSDN page for Process.Modules and this thread there is a known issue in Process.Modules when enumerating 32 bit processes from a 64 bit process and visa-versa:
"only part of a readprocessmemory or writeprocessmemory request was completed" during process.start

"only part of a readprocessmemory or writeprocessmemory request was completed" during process.start

To fix the issue you can do I figured it out. The problem was entirely in my newProc application. It was exiting early because of a args.Len check. The exception that was returned was just misleading and took me on a bit of a wild goose chase.

seems to work fine What actually happened: A user's session was destroyed (i.e., they logged out, or the session expired) while the same user made a request with the same session key.
Why it happened: For example, it could happen if the user had two tabs open, and logged out in one of the tabs, while a request was also made from another tab. If both happened in quick succession then one would hit this error.

I wish this help you for eg. I have two separate requests and both running in different threads then how do I get to know that both are done with their request and completed. , See below implementation , This can help you in detail:
code :
let queue = DispatchQueue(label: "com.learn.swift", attributes: .concurrent, target: .main)
let group = DispatchGroup()

group.enter()
queue.async (group: group) {
    print("1st Thread")
    group.leave()
}

group.enter()
queue.async (group: group) {
    print("2nd Thread")
    group.leave()
}
group.notify(queue: DispatchQueue.main) {
    print("All done")
}

seems to work fine TL;DR
Use zip or forkjoin.
code :
let process1$ = timer(1000);
let process2$ = timer(2000);
let process3$ = timer(3000);

const doSthg1 = pipe(
  tap(() => console.log('Process 1 has finished')),
  map(() => 'Process 1 has finished')
)

const doSthg2 = pipe(
  tap(() => console.log('Process 2 has finished')),
  map(() => 'Process 2 has finished')
)

const doSthg3 = pipe(
  tap(() => console.log('Process 3 has finished')),
  map(() => 'Process 3 has finished')
)

forkJoin(doSthg1(process1$), doSthg2(process2$), doSthg3(process3$)).subscribe(() => {
  console.log('Now I am complete');
});
getInitialData(){
  this._authService.openCorsConnection().pipe(
    concatMap(() => forkJoin(this._authService.x(),
      this._tService.getSystemDate(),
      this._tService.getTemp(),
      this._tService.getSettings()
    )),
    catchError(err => {
      console.log('gor error', err);
      if (err.status == 401) {
        return EMPTY;
      } else {
        return throwError(err);
      }
    }),
  ).subscribe(() => processData());
}
zip(doSthg1(process1$), doSthg2(process2$), doSthg3(process3$))
.subscribe(
      ([x,y,z]) => {
      console.log(`x=${x}, y=${y}, z=${z}`);
});
