["????????" <85358830 () qq com>]

I use the command as you give me:
./snort -G 0 -Q --process-all-events -c ../etc/snort.conf


 The following is the output of the Master snort:

Master snort looks work well.Next step ,I start a new snort instance as client .It looks not load share memory black 
list info,following line is my command:
./snort -G 1 -Q --process-all-events -c ../etc/snort.conf.smg.5.9


It output:

My question is :
1.What does 'Shared memory max instances: 2' mean? It mean I can only start to two instances?
2.How do I know that my snort client uses a shared blacklist?I can't get any infomation from client snort output.

You should use command :

./snort -G 0 -Q --process-all-events -c ../etc/snort.conf

Only instance 0 will be a shared memory writer.

Best,
