It may lead to memory leaks. You don't observe that problem any more because now you never call a destructor for `StMgrClientMgr` (previously `shared_ptr` called the destructor of `StMgrClientMgr` as soon as the object is out of scope or the destrucor of enclosing object is called). To fix the original issue you need to run stream manager under Valgrind, then reproduce the crash locally, then take a look at the Valgrind log to see what is the precise stack trace. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
