store.TakeFullCheckpointAsync(CheckpointType.FoldOver) stucks forever #887

I tried the following line to dump a full checkpoint, and it stucks forever. No error, no exception.

await store.TakeFullCheckpointAsync(CheckpointType.FoldOver)

After changing to the following approach, it works well.

await store.TakeHybridLogCheckpointAsync(CheckpointType.Snapshot, tryIncremental: false);

Why does it stuck?

Hard to say without a repro. It works fine in our tests. Feel free to reopen if you have a stand alone repro to share.
