false alert-mail from different hosts

[Martin Flemming]

Hi !

I've got tonight several alert-mails of 3 host,
which a false, because they've got the data from three other hosts ..

I know it's sounds very strange ...:-(

e.g.

hobbit gives me an alert for HostA,
because the disk is full and special processes are not running,
but if i look into the full alert-mail .. i see some host specfic 
processes which are not from the Host A but insteed from Host B ..

How could this be ? :-c

Any hints ..

Thanks & Cheers
