[BUG-203015] During the use of the Second Life viewer repeated Windows messages that Dullahan_Host.exe has stopped working

[sl-service-account]

Steps to Reproduce

Nothing special, just existing in SL. However it seems that when I was [ADJUST] ing the positions of poses in a piece of furniture using AVsitter 1.05 the messages were very regular, perhaps 5 minutes apart.

Otherwise they come in every hour or so

Actual Behavior

Since upgrading to Second Life Release 5.1.0.511732 (64bit) I have been getting messages from Windows in a popup, that Dullahan_Host.exe has stopped working.

Expected Behavior

The pop up window was totally unexpected.

Other information

I never see this message unless I am running SL and I have never seen it before running Second Life Release 5.1.0.511732 (64bit). And now that I am running this version it occurs fairly regularly.

Hiya Wendi,

Are you only seeing this problem at the location you gave above or does Dullahan_Host.exe crash when you are on other regions too?

I went to the location you gave above & found what I believe to be the chairs using Avsitter (at the end of the pier) & I fiddled with adjusting the poses for a bit but so far I couldn't reproduce Dullahan crashing at that location on Second Life Release 5.1.0.511732 (64bit).

Dullahan is the new system that handles viewer media on the Alex Ivy viewers. At the given location, there is quite a lot of media content within a 128m draw distance, mostly TV screens in the boats & several monitors inside the office in one of the buildings, so I'm wondering if one of the media URLs is causing Dullahan to crash. I notice the monitors in the office are mostly all set to either http://www.metaversetelevision.com/tmz-live/ or http://www.metaversetelevision.com/torleyvision/. These web pages require the Flash plugin to be installed to play, which I don't have installed at the moment, so I'll install Flash (ughs) & see if I can then reproduce the Dullahan crash. https://prnt.sc/i8lq8m

Edit to add: I installed the flash plugin. I still can't reproduce this with all the metaverse TV media playing. I hung around at that location for an hour.

Are you still able to reproduce this problem on the new MediaUpdate-RC viewer at http://wiki.secondlife.com/wiki/Release_Notes/Second_Life_Release/5.1.1.512264 ?

If you can, can you run a session where you reproduce the Dullahan_Host.exe crashing and then quit the viewer. Before you relaunch the viewer, zip up your viewer logs folder & attach it to this issue using More Actions -> Attach Files. This page tells you where to find the logs folder: https://community.secondlife.com/knowledgebase/english/how-to-report-a-bug-r224#Section__3

Which antivirus software are you using? If you whitelist Dullahan_Host.exe with your antivirus software, does this fix the problem? Probably a good idea to also whitelist slplugin.exe.

Thanks :)

My test system: Note I'm on Windows 10 & Wendi is on Windows 7.

Hi Whirly,

I have seen this message periodically since upgrading to this SL client version on many regions. It is only that at the region I qouted it was happening every few minutes instead of every couple hours.

I don't know if the chairs had anything to do with the increased prevelance of the error messages. I have not really found a pattern, only that I'e never seen this message before and since the update I see it nearly every day.

I'm using Norton Internet Security. I've white listed Dullahan_Host.exe and slplugin.exe

I'll run again for awhile on the released viewer and see it this illiminates the error message.

It I get the error message I'll zip up the log files and attach them before I restart the viewer.

Thanks! ~Wendy

Hi Wendi,

I'd like you to try a couple of quick tests. Open the menu Advanced > Show Debug Settings and type in PluginInstancesTotal. The default value 8.

What I would like you to try first, is to set it lower to 4. Then spend some time at that location and see if the Dullahan_Host.exe error occurs more or less frequently, and generally whether your viewer performs the same (more or less FPS).

Next, go into the same setting and set it at 12. Same thing, hang out at that spot and see whether you get errors or other performance issues.

Please press the Info Provided button and let us know.

Thanks!

Whirley,

I had white listed the two executables you recommended and I have been hanging out at the same location. I even spent time adjusting poses in the same chairs, a couple hours now.

I did try the settings to see if the FPS changed and they did not, they swung through the range of about 9 to about 12 FPS - at settings 4, 8 and 12.

Would a test again with the Dullahan_Host.exe OFF the white list be helpful?

Yeah it wouldn't hurt to see if that really did fix it or it's just an annoyingly sporadic issue.

Hi Wendi,

It sounds like whitelisting Dullahan in Norton has helped the issue. Please let us know if this happens again, and in that event, please zip up all your Second Life logs and attach them to this Jira.

Press the Info Provided button to reopen this report.

Thanks!

Whirly,

I removed dullahan_host.exe from my Norton white list and, while I was working as my alt on a product test, I got the error message that dullahan_host.exe has stopped working.

I've attached the zip of the logs folder.

Hi Wendi,

It would be great to know if Second Life 5.1.1.512264 helps to resolve this issue.

Thanks!

Hi Wendi,

Thank you for testing out the newer viewers. We can, though inconsistently, reproduce this issue.

Thanks for the report!
