Too many open files when compress

[XuQK]

Is there thread limit when compress?

I found a error when I use SevenZip.openOutArchiveZip.createArchive to compress thousands small file in my Android:

packageName.utils.filezip.compress.FileCompressor$compressToZip$1$2$1.getStream(FileCompressor.kt:151)

I print Thread.currentThread().name in "IOutCreateCallback.setCompleted", then I'm seeing an increasing number of threads like this:

Thread-1
Thread-2
Thread-3
Thread-4
.

.
Thread-343314
.
.
.

Is this a threading issue? how do I fix it? Thanks

PS: this my IOutCreateCallback.getStream implement, maybe useful:

override fun getStream(index: Int): ISequentialInStream? {
    return if (File(items[index].pathInFileSystem).isDirectory) {
        null
    } else {
        val inStream: RandomAccessFileInStream
        inStream = RandomAccessFileInStream(
            RandomAccessFile(items[index].pathInFileSystem, "r")
        )
        closableList.add(inStream)
        inStream
    }
}
