[Snort-users] Snort spikes to 100% CPU followed by network latency

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?
