Server Deployments

As always, please refer to the server deployment thread for the latest updates and information.

  • On Tuesday, December 13th, the Main (SLS) channel received the same server maintenance package, as deployed to the RC channels in week #49. This includes the following feature requests:
    • BUG-6377 – llGetObjectDetails(id,[OBJECT_ATTACHED_SLOTS_AVAILABLE]) – Returns a value that is number of attachment slots allowed by the server minus the number of attachments worn by avatar. Returns 0 if avatar is not in the same region or if UUID is not an agent.
    • BUG-40871 – llGetEnv() constant “region_object_bonus” – returns the object bonus set for a region.
  • On Wednesday, December 14th, all three RC channels should receive the same new server maintenance package, comprising improved internal server logging.

SL Viewer

The Maintenance RC viewer updated to version 5.0.1.322219, bringing it to parity with the current release viewer, incorporating the Bento updates. This leaves the remaining viewers in the pipelines unchanged from week #48:

  • 360-degree snapshot viewer, version 4.1.3.321712, dated November 23rd.
  • Obsolete platform viewer, version 3.7.28.300847, dated May 8th, 2015 – provided for users on Windows XP and OS X versions below 10.7.

No Change Window

The Christmas and New Year 2016/17 No Change window comes into effect from Friday, December 16th. This means there will be no further server deployments and no further official viewer promotions after that date, through until Monday, January 2nd, 2017.

Issues

Mesh and Texture Rezzing

As noted in my week #49 update, people have been noticing increased delays in object mesh and texture rezzing, with fingers being pointed at the Lab’s CDN supplier(s).  The issues are continuing for some, while for others they appear to have cleared up. It’s still not obvious if it is a potential LL / CDN issue or a network problem in general.

As Simon Linden said in the meeting, the problems have been seen by the Lab, but are proving to be intermittent and hard to pin down. The problem also seems to manifest differently for people: some report very slow texture rendering, other report textures load and render fine, but mesh items are prone to failing to fully render, others report a mix of the two.

Region Crossings

Region crossings have been widely reported as increasing again – including avatars being dumped at 0,0,0 (again). Some are reporting the issue as cumulative: the more regions they cross, the greater the likelihood they’ll encounter a serious issue (becoming unseated, return of vehicle, forced log-out). The usual advice is being circulated – reduce script load, handle crossings with caution, etc. However, the Lab are again aware of the uptick, but have not come to any specific conclusion on the cause.

The avatar appearing at a region’s 0,0,0 co-ordinates appears to be linked to connection problems and / or UDP packet loss (usually the first packet) resulting in messages arriving in the wrong order and the viewer and simulator falling out of synch with one another.

With both the rendering issues and the region crossing issues, fingers have been directed at the increased land impact allowances. This may be a case of post hoc, ergo propter hoc. In particular, it has been claimed that region crossings “became” bad after the mainland LI allowance increase, although people were reporting issues before the LI increase took place.

Appearance Issues / Bake Fails

Some are finding their avatar is failing to render in their view (bake fail) when logging-in. Changing outfits, camming away / back to your avatar may fix this, or a re-log. In extreme cases reverting to the default Character Test avatars may be required, or deleting and recreating the affected avatar appearance folder on your hard drive.

Rider Linden is looking into the problem, and believes it may be due to a missed inventory fetch at log-in, leaving the viewer thinking you’re missing a critical part of your appearance (e.g. your shape), but he is not 100% certain at this point in time.
