3450051 - The sapcpe tool does not run when starting the instance after upgrading the SAP kernel


The SAP kernel is being upgraded, e.g., from release 753 to 754.

After replacing the SAP kernel at the global "exe" folder (/sapmnt/SID/exe/...), SAP is stopped and started again, as usual.

Some instances start with the new kernel, but some still start with the old kernel.

The "sapstart.log" file reveals that the "sapcpe" tool could not be executed and exited with return code 255:

... Local: /usr/sap/SID/SYS/exe/uc/linuxx86_64/sapcpe pf=/usr/sap/SID/SYS/profile/SID_D00_hostname
... system(/usr/sap/SID/SYS/exe/uc/linuxx86_64/sapcpe pf=/usr/sap/SID/SYS/profile/SID_D00_hostname) returns 255
