Hi,
I'm using a batch file to render several maya animation files. after a while, completely randomly, the batch crashes and a popup message appears: "MayaBatch application has stopped working".
when I cancel the popup window it continues to the next file in the batch file queue.
As I said it is completely random, it can happen on any file and on any frame.
I'm using OctaneRender for Maya v1.11b beta and OctaneRender standalone v1.10
Please help me.
Batch render from command line crash

I paste bellow the content of the CMD text after I enabled the verbose mode in the plugin setting, it is only the end part because I can not find the full log file anywhere.
The render crashed on frame 24:

It seems that it is not the plugin crash, as in this case it could be seen in this plugin log. But as I see in this log, the plugin did the work correctly, and just started the render (has set the render-target to the engine)... So, it seems something goes wrong when the engine tries to load the scene to all your cards, as in the last frame the render has even not started (the plugin have never got the image-buffer of 24th frame from the engine)...
Can you please after the crash to look into the directory c:\Users\<User Name>\AppData\Local\Temp\ for the last files MayaCrashLog*.dmp and MayaCrashLog*.log. These may be very helpful to get understanding what is going on.
Can you please after the crash to look into the directory c:\Users\<User Name>\AppData\Local\Temp\ for the last files MayaCrashLog*.dmp and MayaCrashLog*.log. These may be very helpful to get understanding what is going on.

I cannot find those specific files anywhere on my local machine. Please direct me on how can I produce those files while render crashing.

If you can't find them - it is the sign that Maya was not able to create them, and this in turn is the sign that the crash happens outside the plugin, in the engine module...sampakinpa wrote:I cannot find those specific files anywhere on my local machine.

It seems, that you got some platform-dependent issue, as I can't reproduce it on my machine...
Have you checked the GPUs for overheating?..
Can you please try to check the same render with only one GPU core enabled, will you get the same crashes in this case?..

OK, so the gpu temprature are not over heating when the crashes happened, but I did find the AppCrash_mayabatch.exe reports that I included in a zip file attached to this post.
Please take a look at them.
Thanks

Hi
It took more then seventeen hours to render one and a half animation files on one GPU (out of 8) until it stopped, but this time it did not crash but it froze on frame 35 on the second anim sequence. what happened?
I pasting the verbose text on the next post. no crash file this time.
BTW, the only way I could enable one GPU to render, is by disabling all GPU's in the command line switches (-gpu1 0 -gpu2 0...) because those switches apparently support only 4 GPUs' and I have 8. so by disabling all 4 it actually disables all of the 8. then it select automatically one GPU as a default to render.
