Well, the good news is that you've at least narrowed the issue down to server configuration. Unfortunately, my knowledge of multicast troubleshooting is rather limited. Anyone else have any ideas? That said, are you planning on moving to multicast for production? I thought that you were using it as a test. If you're not going to use multicast I would go back to testing this issue via unicast so as to avoid troubleshooting issues that aren't relevant to you.

hi...

the thing is... im having the same problem on my real server... AND on my little test machine acting as a multicast server... So 2 multicast server giving the same error... must be something im missing...

Unicast... as soon as i unicast 4-5 machines or more... the unicast crash... which was working fine in january with casper 8.73... and now with 9.3 crashes...

Bummer of course. Yet, so far as I know 9.3 doesn't really cause this to happen. I know that it's the last thing that was done before the issue but many of us are running 9.3, 9.31 and 9.32. I mean you can try the upgrade to 9.32 (where I'm at at the moment).

With that said, which version of MySQL is your JSS running?

Ahhh... I've personally experienced significant issues with 5.6 as it enforces strict mode as well as a few other funky things. Check out this thread

I stick with 5.5

hi everyone... just to let you know...

downgrading the mysql did not fix our problem...

impossible to unicast the base image for more than 3-4 machines... while back in january with old server 8.73 everything was working fine !!!

im getting bit tired of working on that...

How interesting and unfortunate. I know that the "everything worked in 8.73" thing going on. Can you setup a quick test environment for 8.73 for verification purposes? I happen to know many folks (myself included) that simply aren't seeing the issues that you're having. Something deeper is going on here. Also, (don't flame me for asking) do you have a support ticket open with JAMF? Not that it's the ultimate solution but another set of eyes needs to take a look at your install/network.

At this point I'd even suggest setting up that test JSS if you don't already have one. Even make it it's own netboot and master DP. It doesn't matter how fast or slow it is as it's the number of maintained connections you want to test.

WOW... finally got the solution !!!!

back in january, we decided to publish our share with SMB instead of AFP because of Apple maybe letting AFP go in the future...

The SMB was causing all the trouble... putting all the shares back to AFP, and hop my unicast imaging works fine again and everything goes well

Nice to see you have the solution! Make sure that you figure that one out with how aggressively Apple seems to be wanting to move away from AFP in favor of their own version of SMB2!

It's always something isn't it!
