@changchengx i believe this PR does not release some IB resources which causes other tests on this machine failed on ALLOC_UAR this test allocated too many UAR regions:

[root@swx-rdmz-ucx-new-02 s]# grep uverbs /proc/2143/maps|awk '{print $6}'|sort|uniq -c
    347 /dev/infiniband/uverbs0

[root@swx-rdmz-ucx-new-02 s]# ps -ef|grep 2143
