[Wolfgang]

In my zabbix_server log i see lots of:


016800:20050418:170140 Evaluation of expression [{11240}>5] failed
016800:20050418:170140 Expression [{11240}>5] cannot be evaluated.
030659:20050419:113022 Evaluation of expression [{11253}>5] failed
030659:20050419:113022 Expression [{11253}>5] cannot be evaluated.
030759:20050419:113228 Evaluation of expression [{11214}>5] failed
030759:20050419:113228 Expression [{11214}>5] cannot be evaluated.


What does this mean?
Where does it come from?
What do i need to do to get rid of it?

Thx
