Function does not work in nodejs async

When receiving data, the server freezes, sometimes when receiving other data, it gives only the result from the first function and hangs on the second

async.each(body, function (address, callback){ repository = address.slice(address.lastIndexOf('/')+1, address.length); cmd.get('git clone '+ address, function(data){ child_process.exec('git log --pretty=format:"%ae [%an]"', {cwd: repository}, function(err, stdout, stderr){ console.log(stdout); //выводимый результат на этом останавливается выполнение child_process.exec('rd '+repository+' /s /q', function(err, stdout, stderr){}); } )}) }, function(err){ // All tasks are done now } );
