Bug: Messages skipped during streaming

[tylerhawkes]

Describe the bug

Issue 2351 in the libxmtp repo has missing messages. Those are the result of the node not actually sending the messages.

Expected behavior

All messages make it to the client no matter how many groups or message/group are sent.

Steps to reproduce the bug

run

cargo run -p xmtp_cli --bin stream-monitor -- --output --enable-logging --max-messages 10000

on the tyler/stream-fixes branch of libxmtp against the tyler/stream-fixes branch of this repo that includes some extra logging, none of the missing messages get logged as being handed to the client. All of their neighboring messages (by sequence_id) have 4 messages.

The missing messages (both message ids and sequence ids) are reported on the very last lines of tracing.log wherever the cargo command is invoked.
