#Rendering Errors
3 messages in this thread
I have installed a new machine (486DX4) with 16 meg of RAM for
rendering purposes. On the very first rendering job I was given the
following error message:
Mfree error — validity check failure!
ptr1=85F970, ptr2=85F96C, *ptr1=0, *ptr2=55010000
When I pressed escape (Esc) I got the following message:
HEAPMGMT-heap error #: (ASCII jiberish seen here)
Cheap stack dump linked in=>no dump.
Aborting….
At this point I was at the DOS prompt (no cursor mind you).
I tried running the machine several times in slave mode and it would
come up with a similar message each time. The machine would render
from 30 to 200 frames before coming up with this error. I am trying
to find out if there is a problem with the machine and if so, what
that problem might be. I don't want to take it back to the vendor I
purchased it from until I can identify the problem. Any help would
be greatly appreciated.
The HEAPMGMT error usually indicates that there is a conflict in
memory — primarily TSRs and Device drivers if the memory address
indicated by the error message is in the 640k area, or Disk cache /
ram drives if the error message includes an "EIS" designation.
If this problem doesn't go away with an extremely simple config
/autoexec setup, you might even suspect specific ram chips. (Of
course, it's better to suspect a corrupted program and reinstall 3D
Studio.) If it's ram chips, you can use Phar Lap cfig386
modifications to specify that 3DS use specific memory locations.
These can be tough errors to resolve. Does your machine have a
hardware cache? If that's the case, try turning it off as well as
trying some of the above suggestions.
Nick: Thanks for your suggestions. I'll give them a try….
