Snortsam doesn't make use of any preprocessors. It only blocks on the
rules where you specify it.

What firewall(s) are you trying to block on? Does it block but not
unblock on every IP? You say it only block 10% of the time...what
happens the other 90% of the time? (And are you sure those skips are
outside the repetitive block interval?) Are there any errors in the
Snortsam log file?
