The exec sapstart or sapstartsrv are not working after a filesystem crash

Issue

After a filesystem crash sapstart or sapstartsrv are not working as expected anymore. If you try to execute the sapstart or sapstartsrv command by hand with the user sidadm you get an abnormal ouput.

• Simulated corrupted sapstartsrv

$:/usr/sap/RH2/HDB02/exe> ./sapstartsrv.corrupted -h
Segmentation fault (core dumped)

• Normal behavior of sapstartsrv

$:/usr/sap/RH2/HDB02/exe> ./sapstartsrv -h
Usage:

Run as Service:
  sapstartsrv pf=<Startprofile> [-D] [-u <User>] [-setup_env]
  -D:       Run as daemon
  -u <User>:    Run as user <User>
  -setup_env:   Setup user environment

Installation options:
  -h|-?:    Print usage
  -pf=<Instanceprofile> [-nosystemd] -reg   Register in /usr/sap/sapservices
  -pf=<Instanceprofile> -unreg          Unregister in /usr/sap/sapservices

Internal use only options:
  -pf=<Instanceprofile> -sapparam:  Echo all profile parameters to stdout
  -pf=<Instanceprofile> -defparam:  Echo all default profile parameters to stdout
  -pf=<Instanceprofile> -detailparam [<default profile> [<profile> [<format>]]]:    Echo profile parameter details to stdout
