when taking backups using snapshot if the sstable gets compacted will nodetool snapshot hung?

We are taking backups using nodetool snapshots but I occasionally see that my script pauses while taking a snapshot of a CF. Is this because when it is taking snapshot does the sstables got compacted to a different one so it couldn't find that particular sstable on which it is taking snapshot so it pauses at that particular CF?

Snapshots generated from nodetool snapshot are just hard links on the file system. I doubt very much if this is causing the pause.

I would recommend that you add some debugging to your script to see why its pausing and investigate that way. Many different variables could be at play here.
