Brushing off the dust in here.

Sunday December 15th 2019 04:44:37 am

I have been focused on troubleshooting and finding the source of the lag present on many regions. As such, it has been a while since I have had the time to post here.

A new build will be deployed on all regions that get moved tomorrow. Version build 2. This build will bring the base up to OpenSim Version 0.9.1. Release. This version is available for testing on Unknown. Please use the sky platform at ~8000m to test.

New build.

Friday September 20th 2019 05:19:03 am

Test build 4:
Brings us to OpenSim Master commit, 9ddd2ea
Also included.
1. A new concurrent thread model.
2. A restructured job engine
3. And some tweaks to the Scene Objects to speed up rezzing/deleting.
4. Mysql now uses the concurrent thread model.

These combined should keep sims from lagging when working with large linksets. And should help prevent TP failures, please note, I do not expect this to prevent all failures.

You can test on XTest, Unknown, or Ocean 1. More Sims will be added soon. Please PM Darieth White if you would like your sim added to the test list. We plan to roll this out to all sims, as soon as possible.

Migration update.

Tuesday May 15th 2018 11:33:53 pm

Sim migrations are still going on, however the process proved more involved then expected. Also as the memory leak that had been causing issues on the grid is no longer occurring, the timeline has been slowed down to allow for additional testing.

Migration update.

Saturday May 12th 2018 05:18:17 am

The first sim is now migrated. Gurlywood is live and ready to be tested. Next up is the Sandbox

Resolving a slight network hiccup.
Progress has been delayed. Gurlywood is back running on the old version till i can resolve the network issue.

Migration update.

Sorry for the delay. I had prepared an image ahead of time that failed to connect correctly. And have been fixing the image for the last couple of days. The first sims will be moved later tonight. The first sims, will be tag owned regions. List below. I will post an update tomorrow. Feel free to test any of the moved regions.

Regions to be moved:
Oceans 4-6
The Sandbox

Monthly Maintenance

Wednesday May 9th 2018 03:17:46 am

We are working on increasing grid stability. The first steps have been completed today by updating the grid in general. Starting later today, sims will begin migrating to their own containers. This will keep individual sims from consuming large amounts of ram, and destabilizing the grid. As sims go to their containers, they will start running a new version, the only major change, is this version was compiled on a newer version of mono. There are a few other changes, just typo fixes on the backend. I will continue posting updates here listing which sims will be moved, each notice will be posted 1 hour before the move.
Once the move begins, a notice will be sent region wide that the region will be shutting down to be moved. This will be 10 minutes in advance. Once the shutdown process starts, region logins will be disabled, and everyone will be moved off the region 1 minute prior for a backup of the region. I will contact region owners right before, if they are online.

Weekly Maintenance

Wednesday February 21st 2018 12:04:28 am

This is a standard weekly maintenance. Expected time is ~4 hours.

Additional info:
There is a small box located in the sandbox. I am doing some testing with it. Do not click it, unless you want logged off. Then have fun.
Some minor improvements will be coming shortly to the site.

This has one fix in it.
llHTTPRequest was caped in 0.9 to 2048 bytes. This broke many scripts that used it. This is a hard coded value. So this update was made to fix it. Now the limit is 16384. This the max for most http apps. If your scripts are still broken. Please send me an IM in world.

As to other issues with slow rezzing, and a few other issues. I am working to correct those. In 0.9 they add http throttles. These throttles are intended to keep one person from consuming all simulator resources. However the need some tweaking and adjusting. Testing on will begin on the beta grid in the next few days. Other things are in the works as well. Stay tuned for additional info.

The update is already loaded and running on my sim. It appears to have affected load speeds, this is not expected. However if others see this, please let me know.

1:20am: Testing Complete
1:40am: Grid Shutdown Complete.
1:50am: Scripts/Caches copied to new version.
1:52am: The grid is now starting up.

More upgrades. State of things, and what to expect.

Thursday August 10th 2017 11:34:54 pm

I am sure most have noticed several regions were pushed to 0.9 rather abruptly. This was caused by the last round of OS upgrades to region server 4. After the upgrades, the old simulator software would no longer launch. Rather then spending hours trouble shooting it. I decided the fastest course was to move all sims on the server, to 0.9. This caused a few inventory issues for those sims.

To fix this, I upgrade the Robust(login) server to 0.9 as well. This caused a few hiccups around 11pm grid time. I apologize for problems or inconvenience this caused. After the upgrade, Inventory works much better, this applies 0.8 sims as well. Much to my surprise, The familiar cloud I have been, is no more. I was certain this was caused by driver corruption on my desktop, as it never happened on my laptop. It appears it was in inventory/cache issue for me, as well. So others may see some long standing issues resolved. If you have any new issues. Please submit a ticket. If you are not sure ask myself or Constanza.

Heading forwards, after the weekend I will be fixing search and starting additional 0.9 roll outs as i upgrade servers. The upgrades will be done during the standard weekly maintenance. Occasional rolling restarts may be performed as problems are found and fixed.
