Signatures taking down network

I'm evaluating a Tipping Point box and after gettting the latest
signatures I'm having problems with the box "crashing".  My goal is
not to bash Tipping Point, but instead to gather information on how
often people have seen this type of thing among IPS boxes.

Is there a trend with vendors to roll out signatures as fast as
possible without proper QA?  This brings up a lot of questions about
deploying IPS.  I want two opposite things from my vendors:  1) I want
the latest signatures super fast.  2)  I want proper QA so that it
doesn't bring down my network.  I realize those two things are
contradictory, but I thought I'd throw it out there to see if anybody
had any thoughts.

thanks,
