**Describe the bug (描述bug)** 最近在生产环境出了一次故障，现象是流量扛不住的时候，自动扩容，但即使这样，扩容的部分CPU也会升至100%，即使流量后面没有变化，容器数量近乎是原来的6倍 在测试环境压测了下，复现了。现象是开启了3个容器，其中一个容器在一开始CPU逐渐上升至100%,而其他容器的cpu仍然是20%，在开始停止的时刻，其他两个容器cpu也迅速升至100% 打印了异常的堆栈信息： ` #0 0x00007fa34edd1b5d in read () from /lib64/libc.so.6 #1 0x00000000007e824e in google::ReadPersistent(int, void*, unsigned long) () #2 0x00000000007e892e in google::FindSymbol(unsigned long, int, char*, int, unsigned long*, unsigned long, Elf64_Shdr const*, Elf64_Shdr const*) () #3 0x00000000007e907f in google::SymbolizeAndDemangle(void*, char*, int, unsigned long*) () #4 0x00000000006e8cd1 in butil::debug::(anonymous namespace)::ProcessBacktrace(void* const*, unsigned long, butil::debug::(anonymous namespace)::BacktraceOutputHandler*) () #5 0x00000000006e8d77 in butil::debug::StackTrace::OutputToStream(std::ostream*) const () #6 0x0000000000706f13 in logging::LogStream::FlushWithoutReset() () #7 0x0000000000707350 in logging::LogMessage::~LogMessage() () #8 0x0000000000610464 in brpc::policy::HttpResponseSender::~HttpResponseSender() () #9 0x0000000000613bb4 in brpc::policy::HttpResponseSenderAsDone::~HttpResponseSenderAsDone() () #10 0x0000000000498c10 in xxx:xxxr::SendResponse() () #11 0x00000000004e7fae in xxx::xxx::OnPreLoadFinish() () #12 0x00000000004e6bc7 in brpc::internal::MethodClosure0<yyy, std::shared_ptr<mtad::ssp::PMPPreLoadSession> >::Run() () #13 0x00000000005a1b52 in brpc::Controller::EndRPC(brpc::Controller::CompletionInfo const&) () #14 0x00000000005a1eb0 in brpc::Controller::RunEndRPC(void*) () #15 0x000000000058f9e7 in bthread::TaskGroup::task_runner(long) () #16 0x000000000073f5e1 in bthread_make_fcontext () #17 0x0000000000000000 in ??
