System cannot be stopped after Kernel update, very strange.

[Former Member]

Hi,

the system is running perfectly fine. I have done a Kernel upgrade and i just wanted to stop and start the system one more time.

The stopsap command is not at all finishing (the dots below are running endlessly) and the system is not stopped. You have any idea where to check??

stopping the SAP instance DVEBMGS02

Shutdown-Log is written to /home/biqadm/stopsap_DVEBMGS02.log

-------------------------------------------

/usr/sap/BIQ/DVEBMGS02/exe/sapcontrol -prot NI_HTTP -nr 02 -function Stop

Instance on host p590bnobi stopped

Waiting for cleanup of resources

Hi Krishna Mohan,

We have faced similar problem after kernel upgrade.

Please check whether there is a file  /tmp/.sapstream5<nr>13 (ex:50013 if nr=00) exists or not in /tmp directory, this is hidden file u need to do ls -la to check and it should be owned by the <sid>adm of the system.

And check these notes too

SAP Note 1565645 - SAP composite note: sapcontrol

SAP Note 877795  - Problems w/ sapstartsrv\

Thanks

Hi Pankaj,

one more interesting point - dev_ms file is missing. i checked the other developer traces but didnt find any error. I have uploaded the files in the below link. As i said, the system is running. Only issue is we cannot restart the system. Can i manually create the dev_ms file??

Hi All,

the problem is solved.

The problem was it is not giving any error message rather it is stuck at 'Waiting for cleanup of resources'.

There are two files under work directory - kill.sap, shutdown.sap.

In our system, kill.sap file is empty. Do a ps -ef|grep se.sap and update the kill.sap file with the PARENT id (For ex. kill -2 XXXXXXXX).

Perform again stopsap command and if it is stuck at other instance, just ps -ef and kill the corresponding PARENT id with kill -2. Thats all, the problem solved.

Regards,

Mohan.

Hi Mohan,

Check out the logs dev_ms, dev_disp and dev_w* in the work directory (/usr/sap/<SID>/<Instance>/work . You can check out the latest logs.
