You may have better luck switching to G1GC and using a much larger
heap (16 to 30GB). 4GB is likely too small for your amount of data,
especially if you have a lot of sstables. Then try increasing
file_cache_size_in_mb further.

Hi Cassandra users,
I am getting "Maximum memory usage reached (536870912 bytes), cannot allocate
chunk of 1048576 bytes" . As a remedy I have changed the off heap memory usage
limit cap i.e file_cache_size_in_mb parameter in cassandra.yaml from 512 to
1024.
But now again the increased limit
