LSP0: rolling back apply server 1 是做什麼 ？

發現Oracle 10.2.0.4 Logical Standby中報如下的資訊，然後有大量 LOGSTDBY Apply process P011 pid=79 OS id=9720 stopped 的資訊。
不知道什麼導致的 ？  後來stop sql apply , 重新開啟後正常 。  



LSP0: rolling back apply server 1   
LSP0: apply server 1 rolled back   
LSP0: can't recover from rollback of multi-chunk txn, aborting..
