@jamesge 偶现bthread_worker_usage是bthread_worker_count的2~3倍，一旦出现，就会一直持续，此时服务出现卡顿，api响应很慢，将此服务节点lvs负载关闭，bthread_worker_usage即恢复正常，维持在1左右，再次打开负载，又出现bthread_worker_usage是bthread_worker_count的2~3倍，此时抓取堆栈，如下： Thread 16 (Thread 0x7fe05b9f9700 (LWP 27903)): #0 0x00007fe09056dba9 in syscall () from /lib64/libc.so.6 #1 0x00007fe091ebaa3e in bthread::TaskGroup::wait_task(unsigned long*) () from ./libbrpc.so #2 0x00007fe091ebcb3b in bthread::TaskGroup::run_main_task() () from ./libbrpc.so #3 0x00007fe091eb87ee in bthread::TaskControl::worker_thread(void*) () from ./libbrpc.so #4 0x00007fe090260e65 in start_thread () from /lib64/libpthread.so.0 #5 0x00007fe09057388d in clone () from /lib64/libc.so.6 出现大量上述堆栈信息 重启服务后，打开负载，即可恢复正常。 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
