Hello all,
When I upgraded my grid to 0.7.2, I forgot to activate FlotsamCache (which I
had successfully used in the past). Once I corrected that mistake, something
strange happened: now avatars are always flickering back and forth, refreshing
their textures, and never fully bake. They might show up baked on the viewer,
but other avatars in the region will always see them blank ("white avatars").
Now this is not always consistent. On most sims of the grid, which run CentOS
5.3 (64 bits) and OpenSim 0.7.2 (release) was compiled with Mono 2.6.1, the
problem started as soon as FlotsamCache was activated. On one "test" sim,
running on my home Mac, with exactly the same options on OpenSim.ini etc. (but
compiled under Mono 2.6.4), and FlotsamCache also active, there seems to be
absolutely no problem.
There are a lot of possible reasons for the difference in behaviour, one of
which is that I've added a few more debugging options on the CentOS 5.3 OpenSim
source — I'm still trying to figure out the problems with XMLRPC requests — and
these might have broken something. Or the compilation under Mono 2.6.1 (64
bits) might be slightly broken. Or the Mono compiler for the Mac might produce
better code than the one for Linux (which would surprise me immensely!). Or I
might be hitting a memory limit (I'm using FlotsamCache in memory *and* disk).
Or, well, anything else could explain this behaviour. :-)
Since turning off FlotsamCache is not a good idea (and the alternatives, as
warned on the OpenSimulator Wiki, are not as well maintained...), I filed an
"issue" on Flotsam's page at Google Code —
http://code.google.com/p/flotsam/issues/detail?id=54 But so far I didn't get
reply, so I wonder if anyone in this group has seen this odd behaviour and
managed to do a simple fix. The reported issue adds some more details and a log
of the errors I get under CentOS.
If I hadn't tested OpenSim under the Mac (which runs only a single region, even
though with dozens of thousands of prims), which works flawlessly, I'd
attribute it as a bug :) Because it works well under the Mac, but not under
Linux, I have to assume that the configuration is wrong somewhere. Since the
configuration is exactly the same, it might mean that to properly support
baking under CentOS 5.3 + FlotsamCache, I might have to flip a switch
somewhere, which for some obscure reason is not needed under the Mac. So,
suggestions are welcome!
Thanks in advance,
- Gwyn
