Hi,
i want to import 20000 Document files in node.js.

after 300 exec calls I get:

shell.js: internal error
Error: spawn EMFILE
at errnoException (child_process.js:980:11)
at ChildProcess.spawn (child_process.js:927:11)
at exports.spawn (child_process.js:715:9)
at Object.exports.execFile (child_process.js:607:15)
at Object.exports.exec (child_process.js:578:18)
at execSync (/var/www/filesearch/node_modules/shelljs/shell.js:1793:9)
at _exec (/var/www/filesearch/node_modules/shelljs/shell.js:1130:12)

at FileScanner.ingestDB (/var/www/filesearch/crawl/filescanner.js:41:25)
at callbacks (/var/www/filesearch/node_modules/express/lib/router/index.js:161:37)

I tried it asynchon or synchron. It seems fpr me that the file handle in exec is not closed.

ulimit -n xxx doesn't help here ..

You can reproduce this behaviour with following snippet:

    for(i=0;i<1000;i++) {
        var child = exec('node -v', {async:false});
        console.log(i);
    }

TIA
Michael
