Occasional Node.js assertion error

[robtweed]

Not sure if anyone else is seeing this. Occasionally when clients disconnect I get a Node.js crash:

node.js:27
if (!x) throw new Error(msg || "assertion error");
^
Error: assertion error
at node.js:27:17
at Timer.callback (net:141:29)
at node.js:604:9

Any ideas what's causing this and whether I can work around it?

Possibly due to me using Node 0.3.0-pre?

Thanks

Rob

I have same problem, but can't solve it.

I'm only found this link about this problem:

How to get rid of node crashes ?

[skillcoder]

Problem is still relevant.
Please help.

I'm almost positive this is attributable to a bug in node.js' timer.js that was messing up the linked list of timers every so often. timers.js has changed a lot in the last few months, and this bug seems to have disappeared in the latest versions of node >= 0.3.7

Commit: nodejs/node-v0.x-archive@2ec4cd5

In fact, I've actually just backported the timers.js from 0.3.7 into node.js 0.3.1. It compiles fine and i don't see the bug anymore.
