qnx4 network problem   
There are five nodes QNX4, connected to the duplicated qnx-network. 
n
ameloc program running on each node.

When one of the nodes turn off  the programs to the remaining nodes start to work with the delays.

$sin net
 thinks for a few seconds before starting output.

After a while (10 minutes) of the remaining work on the network nodes to normal.

In what could be the reason and how to solve?

Re: qnx4 network problem   
You shouldn't run nameloc on more that 1 or 2 nodes in a network. If you
want to run nameloc on all nodes, then use the "-s" and "-e" command line
parameters to set the start and end node to the number of that particular
node, then it won't poll the network. eg "nameloc -s3 -e3". You must also
make sure that you have all the netmap files setup correctly on all nodes.

Re: qnx4 network problem   
I tried to follow your recommendations.

In 5-nodes network on every node I start nameloc with
nameloc -s i -e i & 
where i - node number.

Also on every node the same /etc/config/netmap 
refes the addreses of all 5-th nodes of logical 1 and logical 2 networks.


The result is:
- on node 1 the command 
#sin net 
show 1,2,3,4, 5 nodes in network.

- on node 2
#sin net
show 1,2,4,5 nodes in network

- on node 5 the command 
#sin net
show only single 5 node in network.

And global names of task from 1-th node can't locate by qnx_name_licate(0,"name"...) on node 5.

Re: qnx4 network problem   
If node 5 only shows one node, then either the netmap file is incorrect or
you are not running "netmap -f" to read the netmap file.
You must not have the same netmap file on every node. On node 1 the netmap
file should have nodes 2,3,4 & 5 in the netmap file, and on node 2 the
netmap file should have nodes 1,3,4 & 5 etc.
