Thread 266 sip建立过程在等锁
这里在等待 Session_Mngr 的lock_ 锁
此时通过session内存，跟踪锁，发现有几个可疑的地方，筛查出Thread 295线程获取了该锁
而Thread 295线程的queue一直是full的，导致一直卡住，此时无环路锁对应，考虑是否有线程形成死循环导致持有锁一直没有释放
#5 0x00000000005a5951 in ACE_Task_Ex<ACE_MT_SYNCH, MRCP::Message>::putq (this=0x28f4ed0, mb=0x7f7b10008550, tv=0x0) at ../../../share/ace/Task_Ex_T.inl:36
通过this指针：
找到：Thread 324 等subtask_lock_锁。
结合代码：
最后发现：
Thread 250 拿到了subtask_lock_锁
再这里

DTMF流程中一直未收到按键结束，导致锁一直被占用，其他的线程一直拿不到锁
