issue with ksh after updating Solaris 11.4 from 11.4.50 to 11.4.61

Recently I updated the Solaris OS of a SAP system and run in a strange issue. All went fine but if the user sapadm tries to run sapstart the script simply hang.

sapstart is a ksh script. The user sapadm use csh for his environment. It seems to be that the script sapstart does nothing and simply hang.

pstack <pid of startsap> shows a read(6, ...) on top. ptree of <pid of startsap> has no childs.

Is there anyone how has an idea what goes wrong here?

Going back to the Solaris 11.4.50 BE and all went fine again.
