Yes the global limits are OK. I added cassandra to '/etc/rc.local' to make
it auto-startup, but seems the modification of limits didn't take effect. I
observed this as Bryan suggested, so I added
ulimit -SHn 99

to '/etc/rc.local' and before cassandra start command, and it worked.
On Thu,
sorry, probably somebody mentioned it, but did you checked global limit?
cat /proc/sys/fs/file-max
cat /proc/sys/fs/file-nr

as root or your cassandra user will tell you what limits it's actually
running with.

Cassandra is running as root
[root@storage5 ~]# ps aux | grep java

Have you tried running "ulimit -a" as the Cassandra user instead of as
root? It is possible that your configured a high file limit for root but
not for the user running the Cassandra process.

The lsof command or /proc can tell you how many open files it has. How many
