Zabbix can't see IPMI sensors

[gorekBoy]

Hi

I would like monitor CPU temperature on IBM x3550 M4 server via IPMI but Zabbix can't see 2nd CPU temperature sensor.
For 2nd CPU temperature item zabbix says "sensor or control CPU 2 Temp@[192.168.xx.yyy]:623 does not exist"
but for the same item for CPU1 everythings...

we are using zabbix with IPMI monitoring on several IBM x servers with IMM2. everything is working fine, except that there are several situations per day, where following messages appear:

IMM:
