[BUG] 1.5.1: use of closed network connection, 1.5.0 is fine

[bmhatfield]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

After upgrading from websocket 1.5.0 to 1.5.1, my service started regularly erroring with read tcp 10.40.0.207:8080->10.40.0.1:37429: use of closed network connection. Reverting back to 1.5.0 from 1.5.1 quieted these errors.

Expected Behavior

I expected 1.5.0 -> 1.5.1 to be a seamless upgrade, continuing to not error about use of closed network connection.

Steps To Reproduce

This may be hard to reproduce, as I am unsure if this was just unmasked in our code or if a new issue was introduced to gorilla/websocket in 1.5.1. I will update this issue if I am able to find a clean reproduce case. We have quite a bit of supporting code so the bug here could be entirely in our stack, not in gorilla/websocket.

However, a direct upgrade and then revert with no other corresponding changes which results in errors and then those errors going away seems like a good threshold to at least start a conversation.

Anything else?

I reviewed the existing issues and found:

• use of closed network connection #48
• Error: "write tcp use of closed network connection" #439

However both these issues predate 1.5.0 and 1.5.1 by some margin.

I've had the same problem recently, I'll try to roll back to 1.5.0

@simon28082 I'm curious if you can summarize what caused and solved your problem, as I'm experiencing the same symptoms.
