Yes. :)

I agree with you.
Thanks!

Thanks Bongjae. By prefer IPv4, do you mean that if the system had dual stack it would prefer IPv4 and if the system had only IPv6 it would still continue to work with IPv6? If yes, I think that would be fine.
We don't yet have any IPv6-only customer deployments but one can never tell where Shoal would be used and hopefully the above preference would be workable under those conditions.
Thanks

Hi Shreedhar,
I used the invalid URL format of IPv6.
When I saw the following link,
http://www.ietf.org/rfc/rfc2732.txt
I could know that in URL, the literal address should be enclosed in "[" and "]" characters.
For examples,
"tcp://fe80:0:0:0:223:12ff:fe23:d00e%6:4000" is wrong.
"tcp://[fe80:0:0:0:223:12ff:fe23:d00e%6]:4000" is correct.
I fixed the error. :)
In addition, if both IPv6 and IPv4 are supported, IPv4 is preferred.
If your Mac supports IPv4, the branch version will use IPv4's address mainly.
Thanks!

Thanks Shreedhar,
I haven't tested it on IPv6.
I will fix the issue as soon as possible.
Thank you!

My Mac has IPv6 enabled and when I kill an instance in a two instance group, the remaining member gets the following when doing the HW/network failure check during failure suspicion check.
The IPv6 address format or the %6 in the URI is causing the issue :

Okay... my bad.
I hand edited the script file in vi and messed up the else block before the java command.
Got it to run with -DSHOAL_GROUP_COMMUNICATION_PROVIDER=grizzly
and adding the grizzly libraries to the classpath.
Looks very zippy at startup.

Hi Bongjae
I went through past emails on the nice abstraction work you are doing to have transport provider abstracted. I was trying to see if I could run the rungmsdemo.sh script to try out the Grizzly based version.
I added the -DSHOAL_GROUP_COMMUNICATION_PROVIDE=grizzly JVM option to the java command line in the script but I dont seem to be able to run it.
The script quits as soon as I launch it.
Also is the property name correct? Should it be SHOAL_GROUP_COMMUNICATION_PROVIDER with the R in the end. Should grizzly be within quotes?
None of the above work for me btw. Will keep you posted on what I find out. If you have any ideas meantime, let me know.
Thanks for any insights
