My hard and soft limits seems to be ok as well
Datastax recommends [1]
* soft nofile 32768
* hard nofile 32768
and I have
hardnofile 65536
softnofile 65536
My ulimit -u output is 515038 (which again should be sufficient)
complete output
option does not
work :(
I am on 1.0.11 (I know its old, we are upgrading to 1.2.9 right now) and
have about 800-900GB of data. I can see cassandra is spending a lot of time
reading the data files before it quits with java.lang.OutOfMemoryError:
unable to create new native thread error.
My hard
copies.

Centos 6 apparently introduced a default nproc limit of
1024. I raised this for the cassandra user now and hope the crashes are
gone.
