我已在系统设置中关闭了蓝牙,但top
仍然显示它使用了 100% 的 CPU,并strace
显示了大量类似的行:
poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=6, events=POLLIN}, {fd=7, events=POLLIN}, {fd=8, events=POLLIN}, {fd=10, events=POLLIN}, {fd=11, events=POLLIN}, {fd=12, events=POLLIN}, {fd=13, events=POLLIN}, {fd=14, events=POLLIN}, {fd=15, events=POLLIN}, {fd=16, events=POLLIN}, {fd=17, events= POLLIN}, {fd=18, events=POLLIN}, {fd=19, events=POLLIN}, {fd=20, events=POLLIN}, {fd=21, events=POLLIN}, {fd=22, events=POLLIN}, {fd=24, events=POLLOUT} ], 19, 4294967295) = 1 ([{fd=24, revents=POLLNVAL}])
我在十分钟内积累了大约 20,000,000 条这样的行。
这里可能发生什么事?
不确定这是否已连接或者蓝牙是否不可靠,我应该放弃它。https://askubuntu.com/questions/681844/how-do-i-troubshoot-bluetooth

无论如何,我的结论是蓝牙不可靠,所以我放弃了。
