I do have a new issue starting the site however, will need to investigate further later today.
Starting nagios.../omd/sites/home/bin/nagios: error while loading shared libraries: libperl.so: cannot open shared object file: No such file or directory
Might be a missing dependancy somewhere or just permissions.
vm-admin:~ # locate libperl.so
/usr/lib/perl5/5.26.1/x86_64-linux-thread-multi/CORE/libperl.so
