A software program that has been delegated to me occasionally will crash
with Internal Error : Segmentation violation (signal = 11).
I believe I've heard it called the red box of death. Most of the time the
program seems to run fine through these sections of code. I am trying to
find a common cause by having the sotware operators document these crashes
for me. When it does occur the object types are X vs. Y plots being fed data
by variables, records, or collectors.
We also will get occasional Windows error messages stating "90% or more
system resources are in use, blah, blah, blah..."
If anyone has any troubleshooting tips to help me figure how the operating
system memory is getting corrupted please feel free to reply.
The test software was written in Vee version 5 then upgraded to version 6
with Win95/98.

I didn't see the original message posted on the reflector but
funnily enough this morning I inadvertently connected a line incorrectly
causing a segmentation violation error. Instead of outputting an integer
value from a function I accidentally connected the output to a sequence out
pin from an object. The result of this was that the global which should have
been set with a value outside of the function had been cleared and was
undefined and thus caused the error when later called in a formula box.
The main problem here is that with segmentation errors no useful
information to help in pinpointing the problem is given, and therefore a
systematic sweep through the relevant parts of the program is needed to find
the portion of the program at fault. Maybe in your example the error only
occurs periodically due to a certain thread being accessed infrequently. I
find segmentation errors a real headache and I'm sure that more info as to
the cause of the error would be well received by all, if of course this is
possible as I don't fully understand the nature of these kind of errors !
