Hello Henri :)

Since I've read somewhere that you'd like the crashes we have to be reported, I just got one. I was basically doing nothing. Just had tp'd to a new place, waited for everything to rez, then I tried to turn, got stuck (freeze for a couple of minutes with the classic Mac spinning pizza), then crashed violently (window disappearing, Mac OS telling me that Cool VL Viewer had quit unexpectedly). Here is my system info:

I'd need a stack trace log: the normal log doesn't provide any useful info in this particular case.

Also, please note that I can't really guarantee that MAC builds are stable, since I'm not the one building them (I don't even have a MAC to test them onto). I only test Linux and Windows builds.

I saw you asked for it but I couldn't find it anywhere. Maybe it's not at the usual place on a Mac, I don't know where it can be… I'll ask people who might know and I'll try to attach it. Might be for next time though, not sure the previous one has been kept, even if I didn't have any crash since then.

I know that. It was just in case the problem lied in a common piece of code. I'm not expecting anything, it's just to let you know about the crashes I have. I'll provide the full information from now if I can find it. If not, well, I'll just live with them, getting far less of these with Cool VL Viewer than with any other viewer anyway. :)

Thank you!

In fact, I could reproduce a bug dealing with the threaded curl code... Whenever you have "HTTP fetch texture" enabled and set the "Max HTTP requests" setting to 32 (in "Preferences" -> "Network & Web") and have "Multi-Threaded Curl" enabled (in "Advanced" -> "Network"), you can get the viewer to crash while it fetches textures from the network via HTTP... There's apparently some weird thing happening despite the mutex locks in place. I'm trying to figure out the bug, but in the mean time you can either disable "Multi-Threaded Curl" (which will perhaps make the FPS rate "hiccup" each time new textures are fetched) or lower the the "Max HTTP requests" count to 24 or 16 (which will make textures rez somewhat slower).

Are values at 16 or 24 recommended? I think I read something about keeping that value rather low, but that may have been just misinformation of the person who mentioned it.

I use 32 in SL without any trouble (and very fast textures rezzing time as a result). As long as the texture server can handle 32 simultaneous connections per IP (which, IIRC, is the default setting for Apache servers), it's no problem. It could be an issue on some OpenSim grids, should they use weaker servers with a lower capping (in this case, you'd better lower the setting to match so to avoid timeouts: just watch the debug console to see if such timeouts or stalled HTTP transfers happen).

As for the reason why I mentioned this setting in this thread, it was because of a bug in LLCurl that has been since plugged.
