Problem Statement/Rationale

Since using mongo tools 100.15.0, some mongorestore jobs failed with

unable to write wire message to network: write tcp ...: write: broken pipe: connection(...) unable to write wire message to network: write tcp ...: write: broken pipe

On server side we see

recv(): message msgLen 48000026 is invalid. Min 16 Max: 48000000

Steps to Reproduce

I can't share the bump file for which this failed, but I guess using any multi Gigabytes dump with documents around several tens of Ko should reproduce it.

Expected Results

Restore succeeds

Actual Results

Restore fails.
