There is an upper memory limit in Python?
I have 2GB RAM and 2 processors Xeon 2.4 - (Windows XP), but I just can use
1.2G of memory, after this python crashes.
Does someone know if python has some memory limit?

Not deliberately :-) What are you filling all that memory with? What
does "crash" mean? MemoryError, or something more exciting?

You might be surprised to learn that the amount of memory available to a
single process is (almost) completely unrelated to the amount of physical
memory in the machine. Windows is a virtual memory system.
A single process in Windows is limited to 2GB of address space. Part of
that is occupied by the Python executable, your DLLs, and the system DLLs.
1.2GB seems a litle low, but it is not entirely unreasonable.

Why do you say that single process is limited to 2 Gig? I believe that on
windows a single process can run with to 32 bits addressed or 4 Gig of
space. I have run R with over 2 Gig of memory.
Why would python be limited to 2 Gig (including overhead)? I don't see that
python should be any different.

(I responded privately, but thought I should register the answer here,
too.)
No, a user-mode process in Windows is limited to 2GB of address space.
Addresses 80000000 and larger are kernel space. You can change the
threshhold to 3GB by using the /3gb boot.ini switch, but few do so.
You can certainly have more than 2GB of physical RAM in your machine, but a
single process cannot use more than 2GB at a time.

Hi:
I need make a calculation from database and the result may have 20,000,000
records which format is just a string. Can I add them into an ArrayList
object one by one? Is there any upper limitation on ArrayList object?
Even there is no limit, I don't think this is not a good solution. It must
take much memory. Any suggestion?
Thanks

Is there an upper limit to how many Session variables you can
transfer? I'm working on a utility application that passes info from
a web form into a pdf. There's no database access, so I'm using
Session variables, but it's going to end up being a lot of data. Is
this the best way to do it, or is there a better way?

I've some troubles getting my memory freed by python, how can I force
it to release the memory ?
I've tried del and gc.collect() with no success.
Here is a code sample, parsing an XML file under linux python 2.4
(same problem with windows 2.5, tried with the first example) :
#Python interpreter memory usage : 1.1 Mb private, 1.4 Mb shared
#Using http://www.pixelbeat.org/scripts/ps_mem.py to get memory

Hi,
I know that this issue is indeed strictly operating system dependent
but I am just curious:
I have a five dimensional array, whose size sums to 68 MB (almost).
This array is contained by class X. When I simply attempt to create an
instance of that class, I get segmentation fault.
I am working on Solaris (which has 8 KB pages ). What may the case be?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
