Summary :
SAP users may encounter warnings in the SAP Kernel log due to inaccurate timekeeping functions within the Linux Kernel, particularly on systems with high-speed processors like Intel XEON EM64T or AMD Opteron. These discrepancies are reported in activities such as STAT_READDIR, STAT_COMMIT, and STAT_READSEQ. SAP has addressed this issue in newer patch levels which utilize POSIX timers for accurate time measurements, as detailed in SAP note 87447. Users should update both their Linux operating system and SAP Kernel to at least the specified versions to resolve these issues, rather than adjusting SAP instance profile parameters which might diminish performance.
