Hi,

First off didn't see this heading so I did original post in the India Apprentice heading!

I have just started using houdini 17 and it keeps crashing under the simplest of tasks such as switching viewports. Wiped my computer to start again and it did the same. My other programs like Maya and Unreal Engine work fine and so does Houdini 16.5. I can't seem to figure out whats the problem can any one help please? I have put what my log displays below and machine spec:

Hope someone can help as I can't do anything at the moment

Thanks!

Update!

I can now make it crash everytime by doing these steps:

- Go to Right View create a cylinder
- open up the cylinder object node
- set the Z rotation to 90, Height to 0.3 and Columns to 36
- switch to Pespective View
- Edge select the where the cap would be
- add a poly fill, Fill Mode: Triangle Fan, Edge loop ticked and set to 1, Deform Patch unticked
- Repeat the step above on the other end
- Switch back to the right view go over the left and select the white mouse icon and this is when it crashes for me

Hi,

Scrap what I said above it does it randomly with in 5 to 10 minutes. I have been backwards and forwards with Sidefx support who have been really great but still no solution.

Whats odd is Houdini 16.5 works fine but any version of 17 doesn't

Has anyone got any ideas at all because I don't really want to go back to Maya if I can help it!

I've tried the below:

- CMOS Reset
- Fresh Install of Houdini
- Fresh Install of Windows
- Back dating graphics drivers
- removing audio drivers
- disabling anti virus
- underclocking RAM
- Disable HPET
- Disable Core Performance Boost
- Enabling TBBMALLOC_PROXY_ENABLE
- Renaming the Houdini folder in documents
- Unplugging Harddrives and other hardware
- Prime95 stress test - Of which showed a fault but I can't seem to replicate it again

I can't think of anything else to try.

Would a failing Power Supply cause issues at all? The only thing I haven't tested is that but I was thinking that if its drawing to much power and the PSU you can't keep up maybe its causing 17 to crash but its really a shot in the wind

Hope someone can help as its a brilliant software

Kind regards
Joe

Houdini will draw a lot of electricity when simulating and rendering, so it does't sound like it's your PSU by just using the modelling tools. You could try to under-clock the chip or turn off SMT in the bios. At least on Linux, Houdini will usually just lock the machine up and sometimes crash the app if there is too much power draw.

To diagnose, open the Task Manager and view all the CPU cores and to see if there is a spike in CPU usage just before it freezes.

Hi Thank for the reply,

I tried what you said and no, no spikes also tried disabling the SMT and still the same. Its very odd and I really don't know what to do I have tried everything and am at a loss

Thanks for your help though

Hi,

Ok, have u tried running it at 100% to see if its more stable?

I had random frequent crashed when I updated to 17. Similar crashreport mentioning libUI. After troubleshooting for a week I tried setting the UI to default and it hasn't crashed since. I filed a bugreport to SideFX which they acknowledged, but haven't heard back.

Running a super tiny UI is a bit frustrating but its the only solution for me atm.

Hi thanks for the reply,

Turns out I didn't have that enabled so that didn't help which sucks

Thanks though!

Hi,

Update!

I think I've found the issue and reported it to the bugs department. It seems that if I use the “Space + B” combo to switch viewports it then crashes shortly after. If I uses “Space + 1/2/3/4 etc” it stayed stable for 3 hours before I shut it down!

Thought id put it here just incase anyone else gets the issue

Cheers
