[Opensim-users] "Save OAR" stopping since r9700

[John Hopkin]

Interesting - thanks (to both of you).

I'm not what other information is relevant, but here's some:

1. For prims counts, they are two of the largest regions among the
seven, marked with asterisks here:

2889
2717*
 858*
 526
 257
 195
   3

2. In total data size, they're the two of largest, as measured by the
size of the last good backup:

140M*
 31M
 23M*
  7M
  5M
  4M
  0.5M

3. Regarding terrain, as well as location on the grid, they're not
unusual; although they're adjacent to each other, all seven are
located contiguously and contain a mix of elevations.

4. They could well be the regions with the most scripts; I don't know
how I can find that out without a manual audit in-world.

There are four other regions, not normally loaded, used occasionally
as sandboxes and storage areas.  I don't yet know if they're affected
by the bug.

Hope this gives some idea, and maybe helps.  If you want to know
anything else, please ask.
