We haven't seen many issues with whatever code we are running now but early on we had all sorts of problems , in my personal opinion they were the biggest waste of money we have ever done . They don't work worth a darn , ours when we try to use the packet capture capability it takes like 30 minutes for it to come back with the decoded packets and generally just slow as death . Much better off getting a standalone packet analyzer like Observer 10 and then using span .
