Systems that randomly hang when a large number of
applications are running or a single one that is managing a large quantity of
data are frequently troubled by defective memory - random access
memory (RAM).
If there isn't enough, windows sometimes loses it's
mind trying to use the hard drive for back up memory or simply crashes when it
can't find a little RAM to use. Computers are still relatively
primative things in terms of development and they just don't always work
perfectly. Windows machines generally need to be rebooted daily to refresh
memory allocations if they are used intensively.
Second problem might be that a memory stick is
defective. Everything works just find till it hits that last bad flip-flop
at some address toward the end of memory. To test for that, boot the
computer in the same sequence and start applications in the same sequence.
If it hangs pretty close to the same place, but doesn't do it if you start the
troublesome program first, it's probably the memory.
If you have more than one stick, you can remove or
swap locations to see which one is the problem.
Memory is so cheap these days that you can save
hours of frustration just by replacing it and going back to work. I've had
this happen 3 times on different computers only to identify the memory as the
problem after hours of looking for software conflicts or bugs.
Good luck,
Mike

hangs when running test
Hello,
It was written many, many times but here it
comes again: in order to fix the "problem", the problem has to be
reproduced. Problems that can not be reproduced can not be fixed.
I
do not know what formulas/settings you are using, and what you do in AA
(scan/backtest/exploration/ ???) so this discussion is pointless without
seeing actual case details
I wrote this already but apparently this
needs to be repeated:
You would need to provide details to support
at amibroker.com:
- the database (data source) you are using -
formula - trade list - settings file (.abs) - ticker list you were
testing on - set of parameters you claim produce problem,
etc....
