1) Wrong Github repository: https://github.com/zeromq/zeromq4-1/issues 2) Are you using the same socket from multiple threads? 3) Are you closing a message after sending it, without checking if the send failed first? 4) Can you provide a minimal example that reproduces your problem?

@bluca Thanks Bluca. The issue can't reproducible until now. It was used under multiple threads scenario. So, maybe it was cuased by 2 or 3 you mentioned above. I will try to dig out more if it happened again. Thanks!
