ucp_tag_send_nbx: Sender Successful but Receiver Fails to Detect Tag Data

[AVA022]

Hi! I am encountering an issue in my program where it seems that ucp_tag_send_nbx successfully sends data from the sender's side, but the receiver fails to detect the corresponding tag data (packet loss). I am not sure if this is a problem with the tag mode mechanism or if there might be an issue with my code logic.This issue cannot be reproduced consistently

• In other words, is the tag mode function reliable for data transmission?

Could anyone please provide some insights or suggestions on how to troubleshoot this issue?

Hi, the tag mode, as all UCX APIs, is reliable. Can you pls provide the code (or some snippet) to demonstrate how tag API is used in your application?
