Problem with vm.memory.size[free], data will not be saved into table 'history'.

[lehler]

Hi,

Zabbix server version 1.4.6 is running under linux debian etch.
Zabbix client A/B (zabbix_agentd v. 1.4.4) is running under linux debian ecth too.
The configuration from zabbix_agentd und client sytem is same.
From clients I run /usr/sbin/zabbix_agentd --print, it will list all
correct test results.

From server using zabbix_get I can get the data of vm.memory.size[free],
for example:
zbxsrv:~ $ zabbix_get -s hostA -k vm.memory.size[free]
3995246592
zbxsrv:~ $ zabbix_get -s hostB -k vm.memory.size[free]
4152373248

In MySQL zabbix Table 'items' the lastvalue from vm.memory.size[free]
for both hosts is recorded and there is no error.
the data vm.memory.size[free] from hostA is always saved in to table 'history',
but the data vm.memory.size[free] from hostB ist not!
I have checked the table 'history' with itemid (hostid = hostsB) and found
no data in it. I don't know why!

some log protocoll:
cat /var/log/zabbix-server/zabbix_server.log
4164:20091022:093901 Host [hostB] will be checked after 60 seconds
4162:20091022:093912 Expression [{16976}<1] cannot be evaluated [Unable to get value for functionid [16976]]

Can somebody help me? thx
best,
