Not really I'm afraid.
The actual error is the invalid argument bit. It refers to a call to 'semop'. A very quick look at the xymond code seems to indicate that it would be the semaphore id that it is objecting to - basically it doesn't exist or the id is less than zero.
How that came about though, I have no idea. It may be that the code is being called when it shouldn't be - perhaps a lack of argument checking. It would require much further checking of the code to see what is happening. Maybe running xymond is debug mode will give more information.
