How to defeat Error: accept EMFILE?

Question

linux

The problem is as follows:
It is worth node 0.8.14, a script is running that uses sockjs
The server was restarted, and now the following is constantly poured into the script log:

events.js:71
        throw arguments[1]; // Unhandled 'error' event
                       ^
Error: accept EMFILE
    at errnoException (net.js:769:11)
    at TCP.onconnection (net.js:1017:24)

After the reboot I put

ulimit -u 1048576
ulimit -n 1048576

These values ​​were before the reboot
Here is the output ulimit -aso far

Those. just typed in the root console?
ulimit affects the current application and its descendants, it does not affect other running applications and applications launched from other places.
