Continuous msg in syslog: 'zabbix_server: unaligned access to xxx' message in syslog

[Jun.Liu]

Hi all,
I just finished Zabbix 2.2.3(rev 44105) installation on a HP RX2660(IA64), every thing works fine except I found below mass messages in the syslog. Is this normal behavior for zabbix server? these message made the syslog file size increasing rapidly. how can I stop it?
