Steps to reproduce:
In zabbix-server.log file I can see these lines with zabbix-server alpha9
Fixed in development branch svn://svn.zabbix.com/branches/dev/ZBX-14808
query failed:  PGRES_FATAL_ERROR:ERROR: column i.utemid does not exist
LINE 1: ...oin hosts_groups hg on hg.hostid = i.hostid where i.utemid=4...
ZBXNEXT-4119 introduced this: " where i.utemid=" ZBX_FS_UI64,
I guess there is a typo error (u and i are so close on the keyboard)
