When the configuration option "Automatically create monitoring agents" was enabled, the operation "rename host" got stuck indefinitely.

You can recover from this by killing the (second) apache processes accessing multisite.mk and restarting (CMC and apache):

OMD[mySite]:~$ fuser etc/check_mk/multisite.mk
/opt/omd/sites/mySite/etc/check_mk/multisite.mk: 2294054 2294059 2294332
OMD[mySite]:~$ kill 2294059
OMD[mySite]:~$ omd restart
