SAP HANA hangs

[Sapienstar]

Hello, 

We have an issue with an S/4HANA 2023 system. 

(SAP HANA 2.0 SP 07)

It is working fine but after some time the system becomes slower or does not work at all. When the issues start, I see some alerts in alert files in nameserver and indexserver. I have tried searching in the SAP Notes or google using the keywords but no luck. 

I tried to choose some part of the file which might be helpful and attaching it. 

Kindly asking your support if you have any ideas. 

namserver_alert.txt

indexserver_alert.txt

Hi 

1. Could you check all disk free space in HANA DB and SAP USR file system?

2.  Check this SAP note 2889270

Hello Sriram,

there is no space issue. If that was the case I would not be able to start the DB anymore. 

Thanks for the Note. I am checking it, will review the parameters once again. Thanks

Hello, Using the SAP Note, I changed the threadpool from 5 to 1 and it is ok now. thanks a lot. Now, I am having issues from the docstore service which is constantly hitting high CPU, anyway looking into it.

I saw some errors regarding the replication configuration.

The operating system where the HANA system is installed was configured according to SAP recommendations? Is the HANA system with the latest patch installed?

SAP have a tool to help process application logs that could help you: https://supportportal-pslogassistant-app.cfapps.eu10.hana.ondemand.com/utilities/FileTypeList/index.... (Support Log Assistant)

Hello, to my best knowledge the system is configured according to the SAP HANA recommendations. The replication configuration logs are strange as there is no replication in this system.
