The values of the suse linux are
/proc/sys/fs/file-max
206044
/proc/sys/net/ipv4/ip_local_port_range
1024 29999
the total number of handles is 721
I guess the system may be over 1024 limitation.
And I add the followings line to /etc/security/limit.conf
* soft nofile 1024
* hard nofile 2048
root soft nofile 1024
root hard nofile 2048
But, I don't understand what is the different "soft" and "hard".
