i am using Operations Manager 2016 for monitoring a host with Solaris 11.4 OS. after several hours (24 h), host state is changed to gray and i get this text "The Run As account does not exist on the UNIX/Linux Server. " but Run As account is valid. This problem is fixed each time by reset SCOM agent on host. I get this error over and over again. also service log in /var/svc/log/application-management-omid:default.log is normal. thanks.
I finally found the solution to this problem. In my case, this problem is due to the lack of a lsass.so library in the system. The problem was resolved after updating this library and modifying the PAM Configuration file. thanks.
