> We were performing a massive upload of data to our cluster and found, that one of the
nodes is ruuning out of free space
> nodetool ring didn't show any extra usage, but df -h / on the problamatic node shown
us 95% of used space, while other nodes were all around 50%
> Eventually, we discovered that there's an abnormous peak of tmp files in one of our CF's:
753'906'319'257 bytes of data in 26811 files.
> Rebooting the node caused all that files to get deleted and node went back to normal.
> One of the symptoms: when the node started to misbehave and collect the temp files, it
started to flush the memtables due to lot of heap used.
