CallCount++ will eventually break about node-graylog2

Yeah, that's a crazy high number, but you're not incorrect :)
Basically it boils down to being able to send 1 million logs per second per process for 285 years. I hope that anyone logging that much with this library, is willing to put in a PR to fix this ;)

I'm looking into a significant memory leak in your module when running inside of a docker 1.11 container, and there is no graylog server running to accept messages.

I've been able to rule out dgram, going to take a look at zlib next...

[jasonmcaffee]

The memory leak issue is with zlib.deflate.

Just doing this inside of docker (latest node) eats up 1GB of ram on my macbook pro, and it never releases

let zlib = require('zlib');

let message = {
  some:"data"
};
let payload = new Buffer(JSON.stringify(message));

for(var i =0; i < 10000; ++i){
  zlib.deflate(payload, function (err, buffer) {
  });
}

It's also a memory leak without docker, just nowhere near as bad. After that runs, local node process has ~250MB of ram.

As @bnoordhuis explained, this is not that strange. You're deflating 10000 times in parallel. Anyway, unrelated to node-graylog2.

@ronkorving I'm not sure what you mean. Using your package causes our services to crash after about a week of logging (our services aren't heavily utilized at the moment, so its not even a large amount of logging). Your package uses uses zlib deflate. Anyone who uses your package on a Linux system will be affected by this issue.

Let's discuss that in issue #19, where it belongs (and where you can see that I'm all for allowing compression to be configurable). I'm gonna close this one.
