As we’re all (probably painfully) aware, the last few months have seen Second Life plague by region crossing issues, with users frequently disconnected (with teleports – being the most common form of region crossing – in particular being affected). One of the pains in dealing with these issues has been identifying the root cause – with most thinking being around it being a timing issue with communications between the region receiving and incoming avatar and the user’s viewer.
However, speaking at the Content Creation User Group meeting on Thursday, April 18th, Vir Linden indicated that the problem might be related to the server Linux operating system update the Lab recently rolled out.
That update – was initially deployed to a small cluster of regions on a release candidate channel called Cake, and it has been reported by those using Cake regions for testing in April, that it was those regions that first demonstrated the teleport issues – although at the time, they were thought to be local connection issues, rather than indicative of a deeper potential issue.
Commenting on the situation at the CCUG meeting, Vir said:
We’ve been having some issues on the simulator side where people tend to get disconnected during teleports … it’s been common enough that shows up as a significant blip on our stats … and that issue seems to have come along … basically when we upgraded the version of Linux that we’re using on our simulators. so we’ve had to do some roll-backs there, just to try to get that issue to go away.
[But] that pushes out the time-line for [deploying] all the things that are based on … the later version [of Linux] that we’re trying to update to … Hopefully we can get those out soon, but I can’t tell you anything about the time-line.
This might explain the scheduled maintenance witnessed on April 18th, with large number of regions going off-line and restarted. If this is the reason, whether it does see a reduction in the teleport issues with those regions rolled-back remains to be seen. But if data does indicate the region crossing issues have been reduced, then this can only be good news and potentially worth the disruption of the maintenance and restarts.
In the meantime, the audio of Vir’s comments is provided below.
