Node 14 Error: write EPIPE

[aaestrada]

When move my app to node 14.18.1 or node version 14.15.1 i receive errors in the server.

err: { "type": "Error", "message": "write EPIPE", "stack": Error: write EPIPE at internals.end (/path-to-node_modules/@hapi/hapi/lib/transmit.js:322:21) "errno": -32, "code": "EPIPE", "syscall": "write" }

this is the same with @hapi/hapi:20.0.0 or @hapi/hapi: 20.2.1

How to reproduce this error?

If you ran a capacity test with the below config:

concurrency: 1000 ramp-up: 15m throughput: 500

Blazemeter ui will show you errors like:

conection refused, conection reset , server timeout

The origin of the problem is in the transmit file Line 322.

And the application logs will show: err: { "type": "Error", "message": "write EPIPE", "stack": Error: write EPIPE "errno": -32, "code": "EPIPE", "syscall": "write" } And i'll doing my tests with this forked

Thanks, but I asked you to create an issue, not just say the same thing again.

In order to fix this, we need a lot of more details, and preferably a reproducible test case.

Now i update let me know if i can do something more to help with these!

Thanks, this helps a bit. From what you describe, it is an issue that can happen under extreme load.

I would still like some more insight into the server config and route that triggers this. Or is it a generic issue?

Also, what are you using for the capacity test? And you say you move to node v14 – from v12?

kanongil Thanks, this helps a bit. From what you describe, it is an issue that can happen under extreme load. aaestrada Thanks That true! This happen when run a higth capacity tests kanongil I would still like some more insight into the server config and route that triggers this. Or is it a generic issue? aaestrada Yeah that's happen when stress the server with request kanongil Also, what are you using for the capacity test? And you say you move to node v14 – from v12? aaestrada Also that's true in node 12 looks like my app support but in node 14 fail with the request come up for a lot of time.

I'm using blazemeter to run this capacity test

upvoting. Experiencing same errors. Not necessarily under load. Node v16.17.1, @hapi/hapi v18.4.1

I'm getting the same error and it only occurs when the dataset i pass into the document is relatively large. Does anybody have any solutions?
