ошибка записи: EBADF (неверный дескриптор файла) - ошибка записи в файл

Question

Я работаю над приложением, которое записывает файлы каждый раз, когда поступают новые данные от датчика (я получаю около 266 чисел с плавающей запятой в секунду), и я должен хранить данные каждую минуту, поэтому каждую минуту я 'Я создаю новый файл и пишу на нем, иногда, после нескольких часов, я получаю плохой файловый дескриптор, и я точно не знаю, что происходит.Обычно это происходит через 2:30, но это может длиться дольше

    fun startMonitoring() {
        createNewFhirPackageForCurrentMonitoring {
            currentFhirPackage = it
            createNewFileManagers(it)
            shouldWriteLogFile = true
            startFhirPackageChangerRoutine()
        }
    }


  @Synchronized
    private fun createNewFileManagers(fhirPackage: FhirPackage) {
        val currentMonitoring = currentMonitoring ?: return
        val folder = filesDir
                .resolve(currentMonitoring.monitoringName)
                .resolve(fhirPackage.packageIdentifier.toString())
        dataFilesManager = BraincareDataLogFilesManager(folder)
    }

// здесь я меняю файлы каждую минуту

private fun startFhirPackageChangerRoutine() {
        fhirPackageChangerSubscription = Observable.interval(FHIR_DURATION, FHIR_DURATION, TimeUnit.SECONDS).flatMap {
            Observable.fromCallable {
                changeFhirPackage()
            }
        }.subscribe({
        }, {
            BleLogHelper.writeError("Error on Monitoring Package Change", it)
        })
    }

 private fun changeFhirPackage() {
        val closingFhirPackage = currentFhirPackage ?: return
        val closingDataFilesManager = dataFilesManager

        createNewFhirPackageForCurrentMonitoring {
            currentFhirPackage = it
            createNewFileManagers(it)
            closingDataFilesManager?.closeOutputStreams()
        }
    }

// Я продолжаю писать в файл, используяэта функция

private var differentialBridgeSignalOutputStream: ObjectOutputStream? = null
    fun logDifferentialBridgeSignal(signal: BraincareBluetoothDataFrame.DifferentialBridgeSignal) {
        try {
            if (differentialBridgeSignalOutputStream == null) {
                val file = File(folder, differentialBridgeSignalFileName)
                file.parentFile.mkdirs()
                file.createNewFile()

                differentialBridgeSignalOutputStream = ObjectOutputStream(FileOutputStream(file))
            }
            differentialBridgeSignalOutputStream?.writeObject(signal)
        } catch (e: IOException) {
            BleLogHelper.writeError("Error writing DifferentialBridgeSignal data $signal to $differentialBridgeSignalOutputStream $e", e)
        }
    }

Что может вызвать эту ошибку, условия гонки?Это вызывает у меня сильную реакцию, потому что довольно случайно, когда это произойдет
