Describe the bug

Backgroud: #10370

An assert occurs on the server when the client establishes a connection with the server.

What could possibly be the cause?

Steps to Reproduce

  • UCX version used: ucx 1.17

Setup and versions

  • OS version (e.g Linux distro) + CPU architecture (x86_64/aarch64/ppc64le/...)
Linux node223 4.18.0-305.3.1.el8_4.x86_64 #1 SMP Thu Jun 17 07:52:48 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

Can you pls try UCX version 1.18 or master branch? There were few related fixed.

Hi, @yosefe

After I upgraded to 1.18.0, it seems that the communication between 1.17.0 and 1.18.0 is not compatible?
