   Odd. I'll see if I can replicate.
   
   Two things stand out to me:
   
   1. UCX appears to have been compiled without multi-thread support, we do 
request this:
      ```
      [1648461566.472887] [my-test-host:4147425:0]      ucp_worker.c:2118 UCX  
DIAG  multi-threaded worker is requested, but library is built without 
multi-thread support
      ```
      What is `ucx_info -v`?
   2. It appears after initial connect, something is trying to connect an IPv4 
source address to an IPv6 destination address (I would think this is not 
allowed?)
      ```
      [1648462634.576737] [my-test-host:4152820:1]          tcp_cm.c:96   UCX

      [1648462634.576804] [my-test-host:4152820:1]            sock.c:325  UCX

      [1648462634.576828] [my-test-host:4152820:1]       wireup_cm.c:1203 UCX  
WARN  server ep 0xffff94561000 failed to connect to remote address on device 
lo, tl_bitmap 0x40 0x0, status Destination is unreachable
      ```
      Maybe try with `UCX_NET_DEVICES=lo`? (Not sure if that is related.)
