server does not sending community string in snmp requests

[MartinZapa]

Hi,
i have following problem:
zabbix server does not sending community string (public in this case).
If i send request via snmpwalk, then works fine.
I analyze traffic with wireshark, and in packets from zabbix server is not "public" string. And of course they are 6 bytes shorter.

OS: Solaris 10
Zabbix version: 1.4.6
compiled with --enable-server --enable-agent --with-mysql --with-net-snmp --with-libcurl
Anyone some idea? Thx

Martin
