Hi Count, thanks for the report. I visited you region this morning, and didn't have any trouble rezzing objects. But I do see that as recent as Nov 13 20:44 (2 restarts back), objects were failing to rez in the sim. The reason for the rez failures was that the physics engine was nearly out of memory.
You can view the physics memory usage in the statistics bar, under 'Simulator' -> 'Physics Details' -> 'Memory Allocated'. Right now your sim is at 67MB, which is normal. When object rezzing began to fail, your sim was probably approaching the homestead physics memory limit of 256MB; the sim disallows rezzing when it gets within 90% of this limit (~230MB).
This physics memory bloat might be a bug, or it could be expected behavior, depending on what's occurring in the sim. Could you please monitor the 'Memory Allocated' stat in your region, and note which particular activity in the sim leads to a sharp increase in that stat? With details like "Rez object Z at spot Y, then observe that it permanently increases physics memory usage by xMB", we can attempt to reproduce this problem.
Steps to Reproduce
Nothing
Actual Behavior
Since the past 6 days I receive complaints from residents that they cannot rez on their island and receive the following error message:
Unable to create item that has caused problems on this region
Issues did start after Rolling Restart of previous week.
When I go to the island myself and attempt to rez an Object from my Inventory I receive the same message.
Region restart does solve the issue but only temporary for a period of 10 hours. After this period any rez attempt results in the above mentioned error. Also an avatar that logs in directly to the region is naked without any attachments.
Pathfinding is not enabled on this region so this cannot be the cause of the issue either. I did attempt to turn off scripts. I did check for temp on rez objects. I did turn off physics. I did look for unusual behaviour but nothing shows up.
I do know that this is a widespread issue at the moment and many people have this error at the moment on their island. http://community.secondlife.com/t5/Land/12-09-Second-Life-Unable-to-create-item-that-has-caused-problems/qaq-p/1728059
Your support department did attempt to solve the issue by placing the island on a different server. Placing the island on LeTigre server code, placing the island back on normal server code but that did not make any difference. I do not see anything related to performance of scripts that can have an impact on this. Everything was working correct until 6 days ago.
Three support tickets have been openened the past 6 days. Several contacts with support did not make any difference so far. Support did go to the islands to look but was not able to do anything except taking note of the bug themself.
Four members of your support staff were unable to do anything to solve this.
All of them could not do anything.
I have two islands affected by this for almost a week now.
Expected Behavior
Normal performance of your software.
Other information
I would like to see this solved fast as I cannot keep restarting simulators 3 times per day in order to keep them functional.
Thank you
UPDATE DECEMBER 6 2012
Two residents arrive on the island Dreamworld Rhino and commence to terraform on their island. Until the arrival of the residents the island performance has always been ok. The day the residents arrive who are both using the Phoenix Viewer memory consumption goes from 32 MB to 550 MB in a short time cycle. When I am on the island and watch while the residents terraform I see how the physical memory climbs with 100 MB or more in 30 minutes time. In two hours the residents bring the island from 30 MB to 250 MB and make it impossible to rez any objects in the region.
I did find this on the internet: http://pastebin.com/X6r6y5eW
Over a 3 week time cycle no improvement has been made. It is not possible to restart an island every two hours while residents terraform their island until it becomes defunct. When I terraform myself on the island the memory consumption does not move at all, I did test this. This appears to be triggered by the Phoenix third party viewer. This would explain why this issue is not more spread out.
