while tesing, I got erlang_error: "{badmatch,{error,system_limit}},{module,function,3}"?

I am开发者_如何学JAVA doing load testing of my server with number of clients(200, 300, 500, ....3000). For testing I am using windows 64 bit systems and I am running server on one system and clients on another system. All the clients can do connections successfully, but after one minute or two minutes later, server through an erlang:error -> "{badmatch,{error,system_limit}},{module,accept_function,3}" for some server instances and dies those server instances. Can any on have a solution for this ?

Thank you in advance..

It appears that you have hit the system limit on the number of ports you are allowed to open on your system. Have a read of this doc here to see if you can determine what your limits are.

In particular:

Open ports The maximum number of simultaneously open Erlang ports is by default 1024. This limit can be raised up to at most 268435456 at startup (see environment variable ERL_MAX_PORTS in erlang(3)) The maximum limit of 268435456 open ports will at least on a 32-bit architecture be impossible to reach due to memory shortage.

Open files, and sockets The maximum number of simultaneously open files and sockets depend on the maximum number of Erlang ports available, and operating system specific settings and limits.
