2.3RC1 increased spp_stream4: Stealth Activity Detected alerts

Has anyone noticed an increase of spp_stream4 alerts of Stealh
Activity with the new RC version?

The actual message is:
12/01-15:40:43.525043  [**] [111:1:1] (spp_stream4) STEALTH ACTIVITY
(unknown) detection [**] {TCP} a.a.a.a:1187 -> b.b.b.b:8080
12/01-15:40:45.715698  [**] [111:1:1] (spp_stream4) STEALTH ACTIVITY
(unknown) detection [**] {TCP} a.a.a.a:1189 -> b.b.b.b:8080

And the packets have both the Ack and Rst flags set, which isn't
really abnormal as far as I understand.

I can supply the pcap if necessary, it's happening often enough. :)
