memcap maxed out

[Sharif Uddin <Sharif.Uddin () spectrumasa com>]

Hello

I have set stream5 as follows

preprocessor stream5_global: track_tcp yes, \
   track_udp yes, \
   track_icmp no, \
   memcap 1073741824, \
   max_tcp 262144, \
   max_udp 131072, \
   max_active_responses 2, \
   min_response_seconds 5
preprocessor stream5_tcp: policy windows, detect_anomalies, require_3whs 180, max_queued_segs 0, max_queued_bytes 0, \
   overlap_limit 10, small_segments 3 bytes 150, timeout 180, \


however I still get the following in logs. Is this normal?
