Hello, What does >cat /proc/sys/fs/file-max say? -- Alexey

Hi, Could you please send me the result of following command on your system? ulimit -a Currently, I am sure that the open files number is not set to 200000 as you expected. open files (-n) 1024 One thing important you should aware is that the open files number is specific to each console. You can use ulimit -n to set the number as 200000. But it only availble for the terminal you used. So, on the terminal, you can run your program and then it will be OK. Hope my information can help you. Best Regards ============== Alex

Also you should check status of the socket. Possible most of them is in TIME_WAIT state. Is it possible to ask developers to add event about open close event in log file, which should help to resolve this issue. thanks, Serge

Hi, You are on the right track with adjusting the max number of open files. As you may or may not know, /proc/sys/fs/file-max is the global system setting. While ulimit set's per process limits (you can view a processes currents limits by looking at /proc/<PID>/limits. Also, with a sufficiently recent kernel (2.6.36) and util-linux, you can use the prlimit command to dynamically get/set process limits). So what you'd need to be sure to do is: - Set the global limit to a reasonable number over 200,000 (I can advise on this after looking at your systems current usage). - Set the process limit for the thing creating the sockets to a value over 200,000 that will allow for any other files it needs to open. - There is one other setting you will likely need to adjust, the ip local port range, this specifies the first and last port numbers to use for outgoing connections and thus will act as a limit in itself. On my Fedora 20 workstation this amounts to under 30,000. ** UPDATE on the above setting (ip local port range,) ** The ip local port range is actually going to cause you a problem. The port range is limited to 0..65535. This is due to the TCP header using 2 bytes (16 bits) to store the src and dst port numbers. You can of course use multiple source IP addresses each with 60,000+ outward connections. I can advise on the best way to handle this. ** END UPDATE ** Cheers, Andrew
