ReplaySubject问题

Question

不确定我是否以正确的方式使用此功能。我有许多线程正在将项目添加到ReplaySubject中。我想批量写入数据库。在主线程上，我有这样的代码：

while ((x < y) ) {  //Still some items to process
    if (errorOccured == true) {
        replaySubject.onCompleted();
    }   

    //Process 100 messages at a time
    replaySubject.buffer(100).subscribe(list -> dbHandle.setBatch(list));   
} 

但是，RxJava本身由于以下跟踪而崩溃：
