It seems like aisexec only does healtcheks on the last registered component. I
just register the components using the same handle.

my openAis network configuration tests
two nodes (real address changed to protect the innocent :-O)
N1 : 192.168.31.7 Mask:255.255.240.0
N2 : 192.168.31.181 Mask:255.255.240.0
Network address for N1/N2 : 192.168.16.0
/etc/ais/network.conf
bindnetaddr: xxx.xxx.xxx.xxx
mcastaddr:226.94.1.1
mcastport:6000
Both N1 and N2 have the same network.conf content
* If set binaddr to N1
The nodes started. Each reported that they were the only members in the
cluster. Occasionally N2 reported join message from N1 but did not detect the
node as belonging to the cluster.
The test programs worked as should in each node
* If set bindaddr to N2
The nodes did not "see" each other, not even a detection of the other's
messages. However, did not not try the setup too many times so it might just
be due to statistical reasons.
The test programs worked as should in each node
* If set bindaddr to network addr
Started aisexec but did not log as much about node member and such. When
started the test program (testamf1 or testamf4) all crashed, yes aisexec and
the testamfx.
* Paniced, set bind addr to 192.168.31.16
oops now the nodes identified each other and the cluster had two nodes.
Started up components, testamf3 on N1 and testamf4 on N2 and jipii the
components stats changed as if on the same machine.
Working network conf.-
bindnetaddr:192.168.31.16
mcastaddr:226.94.1.1
mcastport:6000
