Robert Stupp commented on CASSANDRA-11521:
------------------------------------------
bq. pages are stored in Netty direct byte buffers
Just to note, that direct buffers are also constrainted by
{{-XX:MaxDirectMemorySize}}. This affects both message buffers (in Netty) as
well as direct buffers allocated by C* itself. Putting too much pressure on
this (basically exhausting the direct memory size limit) may result into OOMs
as well.
(I didn't look at the whole ticket - but this jumped out)
