there are a lot of places in the code where checks are made to see if packet inputs from the client match data in the server. If they don't then it flags a "hack"
In most cases the cause of the badly matched data is in timing differences between the two.
An example of this is if you attack a distant monster.
On the client you are running towards it normally.
On the server it may be that you are running at a different speed so you may be still out of range when the client shows you already attacking. If that happens then you will just see continuous misses and sometimes the server will crap out with the error that you saw.

These checks were put in place mainly to help with debugging so they can be disabled if they cause too many problems. Just search for the source files for the error message then comment out the "hack" code and recompile.
