Subject [GitHub] incubator-hawq pull request: HAWQ-635. QE process does not exit in...

Github user wangzw commented on the pull request:

    If the issue is caused by the exception thrown by RpcClientImpl::getChannel(). The only
chance is that the system run out of memory or fail to create thread.  In either case, you
will see error message "RpcClient failed to create a channel to" in HAWQ log. 
    Please refer the code in RpcClientImpl::getChannel()
        try {
            if (!cleaning) {
                cleaning = true;
                if (cleaner.joinable()) {
                CREATE_THREAD(cleaner, bind(&RpcClientImpl::clean, this));
        } catch ...
    Isn't it much easier to fix this issue by moving ```rc->addRef();``` to the end of
the ```try``` block?
