Hi All,

Consider this post a desperate plea for help. I'll outline as clear
as possible, and ask (beg) that someone can help me figure this out
before I go insane. TIA

Problem:
When I render frames in LW 3.1 my system occasionally crashes. I get
GURU # 81000005 and then task number such as:
	011D4D30	01068BE0	0176FAF8
	0113CD68	0173A428	011C1450
	0104CD78	011C7BC8
	011C7978	011373D0

A program I have defines the Guru # to mean "AN_MEM Corrupt. Corrupt
Memory List Detected In FreeMEM()"

The bizarre part is I can't tell you exactly when this happens?? 
Sometimes I will render about 20 frames then the crash, other times
2 frames then the crash. I have tried to re-render a frame it crashed
on to see if it was something specific to the frame, but it will work
if I render it again. I can not find a pattern, or find the exact
operation that makes it crash.

My Setup:
Amiga 2000HD
GVP 030/25Mhz with 9 megs of 32bit ram and SCSI controller
A2091 board which has 2 megs of 16bit ram
Toaster 1.0 card with 3.1 Software
Syquest 88meg exterbal
350 meg internal scsi drive
50 meg internal scsi drive
I am recording directly to Sanyo 950 (I am not saving frames to any
drive)
Kickstart 2.1 rom
Workbenck 2.1

What I have tried:
I have run every memory check program I can find, and they all report
no errors. 
I have disabled the 2 megs of 16bit ram on a tip that might cause the
problem.
I have moved the memory chips around on my GVP board to see if the
TASK number changes, it doesn't.
Called Newtek support.
Run a memory block program to disable the memory areas reported by
the task numbers.

AND NOTHING STOPS THOSE VISITS FROM THE GURU!!!

Well, if you have made it this far I thank you for at least letting
me vent. If you have any ideas or guesses please let me know.

Thanks much,

When people reported problems like this to us at the store, we always had 
them try a clean startup first.  Disable any programs you run from your 
WBStartup drawer or from your startup-sequence (ARQ, MenuMaster, 
ToolManager, screen blankers, clocks, commodities, _everything_) and try 
again.  This will often solve the problems.  Afterwards you can put stuff 
back one at a time until you find the culprit, which will need to be 
either updated or replaced.

Secondly, that Guru looks suspiciously like one I get with my A3000 
sometimes, usually with old games.  When it happens, I use degrader to 
turn off my cache and privilege errors and give it a second shot.  I 
doubt that it will help (this _is_ LightWave) but what the heck.
