Hi all and sorry for my english.

NG AI R55 + hfa2. Distributed installation. I have management server and two gateways (enforcement modules). These gateways are cluster LoadSharing multicast. I have questions:

1. cphaprob syncstat:

Exterior Updates:                                      
Sent retransmission requests...................  188   
Avg missing updates per request................  1     
Old or too-new arriving updates................  443037

Local Updates:                                         
Total generated updates .......................  484207
Recv Retransmission requests...................  86    
Recv Duplicate Retrans request.................  232   

Blocking Scenarios.............................  0    
Blocked packets................................  0    
Max length of sending queue....................  0    
Avg length of sending queue....................  0    
Hold Pkts events...............................  6174 
Unhold Pkt events..............................  6174 
Not held due to no members.....................  0    
Max held duration (sync ticks).................  1    
Avg held duration (sync ticks).................  0    
                                                      
Timers:                                               
Sync tick (ms).................................  100  
CPHA tick (ms).................................  100   
                                                       Queues:                                               
Sending queue size.............................  512  
Receiving queue size...........................  128  

What is "Old or too-new arriving updates" ? Why "Total generated updates" nearly to "Old or too-new arriving updates" ? And other parameters ("Sent retransmission requests","Recv Retransmission requests" and "Recv Duplicate Retrans request") do not have zero-value ?

I have problem with sync?

So, I think about increase Sending and receiving queues size. Manual says:

#fw ctl set int sending_queue_size 1024

and I see:

set: Operation failed: Invalid argument

#fw ctl

Usage: fw ctl command args...
