[Update 2008-03-07 01:00] The rolling restart is complete. (Update: the date on this was wrong…the rolling restart finished on 2008-03-07 01:00, not in the future!)
[Update 2008-03-05 19:10] The mini-roll to ~500 regions is done.
Following the completion of the Second Life server update to the 1.19.1 server code, the following issue was reported:
We’ve investigated the issue and have identified the cause. In the 1.19.1 server code we tightened up some bounds checking for string copies within the LSL string operations. After identifying this as the source of the performance degradation, we identified a fix – which maintains the bounds checking, but also surpasses the performance of 1.19.0 by approximately 10%.
The fix needs to spend some time getting tested on Wednesday. Assuming testing goes well, we plan to roll out the updated code to the servers starting with approximately 500 regions (3 racks), then pausing to make sure no unforeseen issues arise. The roll will complete to the rest of the servers on Thursday evening.
The updated server code will also include additional instrumentation to help us track down the cause of the elusive “logged out on failed teleport” bug (SVC-972).
