Unable to see shared write activity when more than 50 laptops on school presence

[wad]

We were testing access points today, and while we had 60 laptops connected to a school server I decided to try sharing a write activity between a few laptops. I started write on a couple of laptops, and shared them with the neighborhood. Some of the machines were able to see one of the shares (maybe ten or so ?) but none were able to see the shared write activity from the other laptops. Both laptops were running gabble (checked with olpc-netstatus).

As I had been testing this last week with success at up to 50 laptops, we performed the test again. We shutdown all of the laptops, then started 35 of them up. With this number of laptops, we were able to see shared write applications and join them just fine.

Build 703, MP machines, build 161 on the school server. Write version 55.

Sorry, no logs, but I will try to reproduce in mesh testbed ASAP.

Would be worth to check if you can see the sharer of the activity or not. If not, that could be a consequence of a "buddy not displayed on the mesh view" bug.

The script attached to #6918 could help.
