I though 2.0.1 was still a bit of a tricky business? If it's<br>reasonably straightforward now, I'll definitely upgrade.

It's been like<br>>>>this for several weeks, across various releases up to and including<br>>>>8131. I'll briefly describe
the symptoms here in the hope that<br>>>>someone might be able to point me in the right direction.<br>>>><br>>>>1. When it happens, the server is usually up and running, and it's<br>>>>much more likely to happen when two avs are logged in (I've not tried<br>>>>any more than two) than with one. It can also happen with only one,<br>>>>or with none, and sometimes happens while scripts are still loading<br>>>>after starting the server, sometimes after an hour or so of running.<br>>>>Sometimes it can be left on overnight with no logins and it'll be<br>>>>fine.<br>>>><br>>>>A typical scenario would be one av being logged in without problems<br>>>>for quite a long time; when a second av logs in, the server locks up<br>>>>within seconds. This, however, is not a completely universal rule,<br>>>>just the most common of
the many scenarios.<br>>>><br>>>>2. What happens is this: the region server stops responding at the<br>>>>command line, and nothing more will happen until it's killed off.<br>>>>Clients get logged off after timeout. On a system monitor, one<br>>>>virtual CPU (it's a P4, so single-core, but with hyper-threading there<br>>>>are two logical CPUs) is going flat-out at around 85-95%, the second<br>>>>CPU idling at around the normal 30%. This persists until the process<br>>>>is killed. Memory usage continues as normal. around 30-50% of the 2GB<br>>>>total.<br>>>><br>>>>3. The server is running in grid mode, with UGAIM services provided<br>>>>by OSGrid, on a Ubuntu 8.10 server with Mono 1.9.1. There are four<br>>>>regions serviced by one copy of OpenSim.exe. Scripting is XEngine,<br>>>>physics
ODE/Meshmerizer. There are around 2200 prims in all, with<br>>>>perhaps 400 mostly idle scripts.<br>>>><br>>>>4. Eliminating each of the regions in turn seems to alleviate the<br>>>>problem to a certain degree - most of the time, any single region may<br>>>>be run with less problems than all four, but there is little pattern<br>>>>to this in the longer term. In the short term, it may appear that a<br>>>>particular region is at fault, but after a day or two the situation<br>>>>may change.<br>>>><br>>>>5. Disabling scripting doesn't seem to have much, if any effect. No<br>>>>script is doing anything particularly exotic, and all are normally<br>>>>waiting for events.<br>>>><br>>>>6. Another thing which sometimes (but not always) helps is to remove<br>>>>the mostly recently-rezzed
prims.<br>>>><br>>>>7. I've tried reinstalling Ubuntu, and I've also moved the whole<br>>>>thing from one machine to another during this time. OpenSim has been<br>>>>upgraded roughly weekly to the latest stable version hosted by OSGrid.<br>>>><br>>>>It's hard to eliminate anything, because the situation changes so<br>>>>often; it may appear to run fine for several hours, with two avs<br>>>>making moderate use of the sims for building, etc, then it may barely<br>>>>run at all.<br>>>><br>>>>If any of this looks familiar to anyone, I'd be very grateful for any<br>>>>help. I think you can imagine how frustrating this has been for<br>>>>myself and my partner, being almost completely unable to progress with<br>>>>our plans for building the regions into the land of our dreams. And<br>>>>it's particularly
galling because of the lack of consistency - we<br>>>>never seem to be able to narrow down the cause of the problem.<br>>> --<br>>> John Hopkin<br>>><br>>> _______________________________________________<br>>> Opensim-users mailing list<br>>> <a ymailto="mailto:Opensim-users@lists.berlios.de" href="mailto:Opensim-users@lists.berlios.de">Opensim-users@lists.berlios.de</a><br>>> <a href="https://lists.berlios.de/mailman/listinfo/opensim-users" target="_blank">https://lists.berlios.de/mailman/listinfo/opensim-users</a><br>>><br>>_______________________________________________<br>>Opensim-users mailing list<br>><a ymailto="mailto:Opensim-users@lists.berlios.de" href="mailto:Opensim-users@lists.berlios.de">Opensim-users@lists.berlios.de</a><br>><a href="https://lists.berlios.de/mailman/listinfo/opensim-users" target="_blank">https://lists.berlios.de/mailman/listinfo/opensim-users</a><br>--
