   look at org.apache.rocketmq.store.ha.HAService.HAClient#dispatchReadRequest
   ```
   // 读取slave本地的最大偏移量
   long slavePhyOffset = HAService.this.defaultMessageStore.getMaxPhyOffset();
   
   if (slavePhyOffset != 0) {
       // slave最大偏移量应该与master传过来的偏移量相等，保证同步消息连续
       if (slavePhyOffset != masterPhyOffset) {
           log.error("master pushed offset not equal the max phy offset in slave, SLAVE: "
               + slavePhyOffset + " MASTER: " + masterPhyOffset);
           return false;
       }
   }
   ```
   
   this ensures the slave offset should be continuous. Thesituation you describe is unlikely to happen, can you give more details ??
