[RESOLVED - JUN 28th, 2008 02:30AM PST]
This issue is now resolved, and items from the message history are delivered promptly again.
[UPDATE 3 - JUN 9th, 2008 11:30PM PST]
Just a quick update to let you know this problem with the message history is still happening. I’ve opened the support ticket with Linden Labs and a bug report has also been filed. This issue is also affecting several in-world vendors, SLExchange, and a lot of other external apps. You can track or vote for the issue at http://jira.secondlife.com/browse/SVC-2462.
[UPDATE 2 - JUN 7th, 2008 02:30AM PST]
Effects from the yesterday’s Second Life network outages seem to have cleared, although some deliveries from the message history are still very slow while your Controllers are catching up on overloaded queues from the last few days.
[UPDATE 1]
Second Life is currently experiencing severe network problems. Please do not try to send any important messages until they post an all clear.
Current grid stability issues, service interruptions and rolling restarts are currently affecting item deliveries from the message history - sometimes it might take up to a few minutes for the item to deliver, some deliveries might also be failing.
Even though normal message and item deliveries (if you send a message to your group) shouldn’t be affected, please not that some of your members might not receive the message in case they are in a problematic region, or their region is in the middle of a rolling restart or updating.
If you have an important message, I suggest you wait until the current rolling restart cycle is over.
I will post an update once the message history is working reliably and without issues again - until then, your members will receive a short note about the issue whenever they request a past item from the message history.
Thank you for your patience and understanding!
