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

Hi there,
After I changed compaction strategy to 'leveled', one of my nodes keeps
reporting 'too many open files. But I have done some configuration

The lsof command or /proc can tell you how many open files it has. How many
is it?
--nash
[root@storage5 ~]# lsof -n | grep java | wc -l
5103
[root@storage5 ~]# lsof | wc -l
6567
It's mentioned in previous mail:)

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.
