Cronjobs getting called multiple times about schedule

[maxpeterson]

FYI: I found that adding a name fixed my duplicates

  @Cron('*/10 * * * * *')
  async test() {
    this.logger.log('Test unnamed');
  }

  @Cron('*/10 * * * * *', { name: 'test-named' })
  async testNamed() {
    this.logger.log('Test named');
  }

=>

[Nest] 9525   - 13/04/2021, 17:30:39   [NestApplication] Nest application successfully started
[Nest] 9525   - 13/04/2021, 17:30:40   [ScanService] Test unnamed
[Nest] 9525   - 13/04/2021, 17:30:40   [ScanService] Test named
[Nest] 9525   - 13/04/2021, 17:30:40   [ScanService] Test unnamed

[Nest] 9525   - 13/04/2021, 17:30:50   [ScanService] Test unnamed
[Nest] 9525   - 13/04/2021, 17:31:00   [ScanService] Test unnamed
[Nest] 9525   - 13/04/2021, 17:31:00   [ScanService] Test unnamed
[Nest] 9525   - 13/04/2021, 17:31:00   [ScanService] Test named
[Nest] 9525   - 13/04/2021, 17:31:10   [ScanService] Test unnamed
[Nest] 9525   - 13/04/2021, 17:31:10   [ScanService] Test named
[Nest] 9525   - 13/04/2021, 17:31:10   [ScanService] Test unnamed

The order of the log entries makes it a bit confusing, but if you look at the time stamps you can see it calls Test named once every 10 seconds but Test unnamed twice every 10 seconds

Also it seems to be that if this is an underlying issue in https://github.com/kelektiv/node-cron then this won't be fixed quite soon since the project isn't really maintained anymore. See here kelektiv/node-cron#578

Let's track this here kelektiv/node-cron#489 (comment)

For me adding a name unfortunately doesn't fix the issue. I still get duplicates

@maxpeterson Thanks a lot man, it seemed silly at first but I did add a name and it solved the issue and it's running just once now. Thanks a lot I've been stuck with this from last couple of hours.

@maxpeterson Yes, thanks a lot. It worked for me too :)
Just added a name: @Cron('10 * * * * *', { name: 'redis' })

@kamilmysliwiec then the bug is still present in @nestjs/schedule, isn't it?
