I am hoping the problem that I am describing is user induced; but I will be
wecoming all inputs...
My app runs on IRIX6.2 on an Onyx w/ 256M memory. One platform has 2 RM4
boards and 1 platform has 2 RM5 boards. The app is loading a terrain
database that contains a total of 64M of texture. I am not currently doing
any active database management (like with pfDBase). I am letting IRIX/
Performer handle the Texture memory management as my app moves through the
database.
The problem is that there an apparent memory leak. If I run my app with a
terrain database that contains < 4 MB texture. This memory leak does not
occur. Additionally this memory leak does no occur on my O2. (yes, yes, I
know the O2 has different graphics HW etc.. ) Which is why I think that
this problem I am experiencing is down in the RasterMemory memory management
scheme. Additionally this problem can be reproduced on any similiar HW
platform. Some other obvious observations include that leakage rate
accelerates as I increase the number of different camera views drawing the
Terrain view. Is there a patch(s) that I am not aware of?? Has anyone
else attempted overload the RM memory w/out activly managing the database
(e.g. pfDBase)....
Any insight/ opinions etc will be welcome...
Thank-you.
