Snort spikes to 100% CPU followed by network latency

Hello, We have been running snort in-line for over a year now with no issues in terms of latency or CPU usage. Recently (over the past month) snort will all of the sudden spike CPU usage up to 100% and network latency becomes real bad, 1000+ms. I am really not sure where to start on figuring out what is causing this. I am starting snort so it prints the alerts/drops on the console and don't see any specific rule that would be causing this. Any advise on this issue?
