This error message i get when i try to start the cyrus master.
This is verry irritating because it gets my mailserver to not accept mail anymore![/code]

this is the result of 'master' trying to execute code from a non-executable region, seems like the data section or heap. since the code it was going to execute looks more like garbage (0, some address, 0, some address, 0...) than actual i386 machine code, it's unlikely this is correct behaviour. in short, this is probably an application bug and you should report it to the original author(s).
