[ 619s] ================== 337 passed, 2 xfailed in 135.00s (0:02:15) ==================
[ 619s] /usr/bin/xvfb-run: line 186: kill: (2874264) - No such process
[ 619s] error: Bad exit status from /var/tmp/rpm-tmp.JVhvHU (%check)
[ 619s]

根据报错信息显示：该问题并不是2个 xfailed用例导致的失败，编译成功的日志中也存在这两个xfailed，xfailed属于用例的预期结果，不影响后续的执行也不会报告执行结果，编译成功的日志见：（https://build.openeuler.org/package/live_build_log/home:liyanan:branches:openEuler:22.09:Epol/python-mpmath/standard_aarch64/aarch64）。

该问题是由于执行/usr/bin/xvfb-run脚本的186行时 kill xvfb-run进程的时候，由于环境未做清理导致启动服务重复，kill到了不存在的进程，导致编译退出，该脚本不属于python-mpmath提供，与该包功能无关

补充说明：
也可以通过修改spec中测试执行方式来规避该类问题
修改前：
%check
cd build/lib/mpmath/tests/
xvfb-run -a pytest-3 -v

修改后：
%check
cd build/lib/mpmath/tests/
py.test
