If you get into a fallen-and-cant-get-up scenario like this, I suggest
a rolling restart of nodes, and on each node:
(1) shut it down
(2) removed saved caches
(3) start it
The problem was fixed by _decreasing_ heap size and applying changes
on the least loaded node.
Tyler, where saved caches are stored? /var/lib/cassandra/saved_caches?
Would it help relieving heap load?

You could also delete any saved caches, which might give you some more
breathing room.

Can you temporarily increase the size of Heap and try?

Hi everybody,
We set row cache too high, 1 or so and now all our 6 nodes fail
with OOM. I believe that high row cache causes OOMs.
Now, we trying to change row cache sizes using cassandra-cli update
column family command but Cassandra nodes keep dying.
Any help is appreciated, it's a product
