系统为SAP46C+DB2+AIX，今天我用KILL  -9  17156命令中止了SAPOSCOL进程（SAPOSCOL进程的进程号是17156。我不是用SAPOSCOL -K命令中止的），然后我执行SAPOSCOL -L，提示“THE  OS COLLECTOR IS ALREADY RUNNING”，但是当我执行PS -EF |GREP SAPOSCOL，却没有发现SAPOSCOL进程的存在。然后我执行SAPOSCOL -S，提示如下：
adm 4> saposcol -s

请问这是怎么回事？

sap notes 548699 FAQ: os collector SAPOSCOL
下面这段比较符合情况
6. Question: How do I stop saposcol if standard commands (points 2
and 3) do not work (Unix)?
Answer: Sometimes it may be impossible to stop saposcol either by “saposcol -d” --> kill or by “saposcol -k”. The system produces messages similar to:
can't kill process 34570.
kill: No such process
ERROR:No reaction from collecting process 34570!
       Please kill collecting process.
Although no process with PID 34570 exists, the output of command “saposcol -s” shows that saposcol is running and shared memory is attached. In this case, you can execute command: "cleanipc 99 remove".
If this does not work either, it is possible to stop the collector running by removing the shared memory key of saposcol.
