Error: value is out of bounds

[dtrackd]

First of all, thank you so much for your awesome activity on the tracker project I want to start using this software for an open tracker project we have going which is getting a ton of traffic

Here is the current error I am getting after running the tracker for ~1min:

root@box:~# bittorrent-tracker -p 80 -q

/usr/lib/node_modules/bittorrent-tracker/lib/swarm.js:0
(function (exports, require, module, __filename, __dirname) { module.exports =
^
RangeError: Maximum call stack size exceeded

Also at some I get this:

root@box:~# bittorrent-tracker -p 80 -q

buffer.js:705
    throw TypeError('value is out of bounds');
    ^

    at Server._onRequest (/usr/lib/node_modules/bittorrent-tracker/server.js:329:10)

Please do let me know if there is anything more I can do to help debug these issues

Thanks

How much traffic are you sending to the tracker? I've never seen these errors before.

I just put in a check to prevent the second error (released as 3.5.1), but I can't figure out the first error.

[dtrackd]

The testing I am currently going through is around 1 million odd peers. But for production I am truly hoping the tracker will handle ~40 times that.

Currently using OpenTracker (https://erdgeist.org/arts/software/opentracker/) but its reaching points where its blocking and rejecting peers on a single machine. Kinda hoping this would be better.

Also getting the same error at slightly different position now.

How are you testing with so many peers? Can you share your script? We should add a benchmark program to this repo so we have a way to measure progress and make sure all changes either improve or don't affect performance.

Doing 40 million peers would be quite an achievement.

[dtrackd]

@feross Not using a script. this is real world traffic. We run 2 trackers, one far bigger than the other.
We are using the smaller one to testing this tracker application.

the smaller tracker is deprecated and hence I use it for testing, getting around 1mil odd peers, the other tracker is in production and currently we handle around ~35mill peers at peak and with the expectation of that to grow.

I will be more than happy to share our server's details (for the deprecated smaller tracker) if it will help you debug more the application while its under constant use feel free to email me at <track (at) demonii.com>>

[feross]

Attempted a different fix for "Error: value is out of bounds" that should be a more permanent fix. Let me know if you see that error again.

[dtrackd]

Thank you for the amazingly quick replies.

I have not gotten any more "out of bounds" errors. how ever now I am getting a few RangeError: Maximum call stack size exceeded instead.
Is this an issue on my debain box? is there any limits or some configs I need to raise on the OS level in order to eliminate these?

Thanks again here are the different errors I have been getting:
