The output of "ps -ef" not also includes the command but also the process age and process arguments. Both can have digits in its string which may interfere when grepping for an instance number like 00 or 01. To fix this, let ps print only the executable with its path. Example: ps with default output - 2 lines match where only 1st line should match /usr/sap/A22/D01/exe/sapstartsrv pf=/usr/sap/A22/SYS/profile/A22_D01_sapa22u01 -D -u a22adm /usr/sap/A22/ASCS02/exe/sapstartsrv pf=/usr/sap/A22/SYS/profile/A22_ASCS02_sapa22u01 -D -u a22adm Example: ps with custom layout, only one line matches as expected /usr/sap/A22/D01/exe/sapstartsrv

I was wondering why the gathering of SAP facts was unstable. While digging through the sap_facts.sh script, I've figured that there is an issue with the ps command output. The name of the SAP instances, like 00 or 01 etc., can interfere with the process age or even with arguments.
I had to revise my code change. At first I used "ps -eo command" to prevent any interference with the process age. But later I figured it can also interfere with arguments. So I revised my patch to use "ps -eo exe".
