Hi,
I am trying to run a simulation in C on my Win2K-machine (the simulation
runs perfectly on a Linux-PC)
The problem seems to be that with certain parameters, I get some huge
3-dimensional arrays that require like 20-40MB RAM.
When I have a size of about 22MB the simulation works fine, when I
increase the array size by ~1.33 (should then still be below but close
to 32MB) it doesn't start with the error message
C:\cygwin\home\clevorn\wlan15\Main.exe: *** Couldn't reserve space for
cygwin's heap (0x20030000) in child, cygheap, Win32 error 487
I tried two solutions posted in this mailing list for similiar problems:
first:
the "gcc -Wl,--heap,50000000,--stack,--50000000 ..." solution
here the simulation fails at small array sizes too.
second:
the "gcc -mno-cygwin ..." solution
here the program does start, but the only thing that happens is, if you
look in the task manager, the process slowly "collects" memory for about
90 seconds until it recaches 32MB (33xxxkB) and than the process crashes
with the windows message " the exception unknown software exception
(0xc00000fd) occured in the application at location 0x6104b9ef". During
that time the VM Size increases with the same rate, only it start at
values like 4xxMB or 6xxMB, depending on the array size (I have 1 GB RAM
so the pure size of these value isn't the real problem).
I think that the size of slightly below or even above 32MB is the cause
of the problem. Is there a general problem with cygwin and running
programs that require this amount of memory. Is there a way around this
problem.
Thanks for yor help!
Regards,
Thorsten

Have you seen this thread about "heap error" from Dierk Bolton?
There might be more messages, I just grabbed the first one I saw.
Try searching google with
heap error site:cygwin.com

>>>>
Thanks, that was exactly to the point. I intended to close each socket but
placed the close statement
into the wrong control block, therefore the socket was only closed when the
server could actually establish a connection to the math-doing client. Most
of the time, however, the client was not done yet with the simulation and
not accepting connections, and the close statement was not executed, thus
creating an increasing number of open sockets! Bad. Anyways, thanks to your
statement explaining the function of this heap, the problem was found
quickly.
Cheers,
Dierk

Each Cygwin app gets a special heap area to hold stuff which is
inherited to child processes. Eg. all file descriptor structures
are stored in that heap area (called the "cygheap"). The cygheap
has room for at least 4000 file descriptor structures. But - that's
the clue - it's fixed size. The cygheap can't grow. It's size is
reserved at the application's start and it's blocks are commited
on demand.
For some reason your server application needs all the cygheap
space when running under the described conditions.
Just a guess: Does your server forget to close file descriptors?

You're right. Just two messages. There have been multiple messages
with this particular error, however. The other message was from a
different person.
Now that we've clarified that, perhaps it would be prudent to kill this
thread.

I tried that. It works fine without the arrays (simulation size ~2MB), but as
soon as you use even the smaller arrays (that worked with cygwin) it fails. The
error message (the same one as above "unknown software exception (0xc00000fd)")
pops up immediatly, the process doesn't seem to "collect" memory. When compiling
with MSVC I get the warning about a too large image size of 4xxMB, or so. I am
also trying to avoid MSVC because I need to change the program (add additional
h-files,...) when using MSVC.
Another interesting thing I noticed is that the simulation runs faster on a Linux
550MHz than on a Win2K-cygwin 1Ghz.

Thorsten

Is there a problem with the mailing list, or maybe on my client side?
I have only received two messages on the list from Thorsten...
I can't tell if you guys are just cluttering the list
with off topic duplicate messages and joking around,
or if maybe I am not receiving all the cygwin emails.
Please clarify :-)

Ah good. Looks like the mental filter I recently installed only needs
minor tweaking to be completely effective then! ;-)

Was it just yesterday? It seems like this message has been repeated every
few hours for the last several days.
Hmm. Speaking of that, it's about time for some more "How do I get
syslog to write to a file on NT" email as well.

As -mno-cygwin uses native M$ libraries it seems likely that the problem
is not of cygwin's making.
Does it work when compiled with MSVC ?

How is this message different in content and substance from the one you

* problem with heap, win32 error 487

Hi,
I am trying to run a simulation in C on my Win2K-machine (the simulation
runs perfectly on a Linux-PC)
The problem seems to be with the memory rquirements.
With certain parameters, I get some huge
3-dimensional arrays that require like 20-40MB RAM.
When I have a size of about 22MB the simulation works fine, when I
increase the array size by a factor of ~1.33 (should then still be below
but close to 32MB) it doesn't start with the error message
C:\cygwin\home\clevorn\wlan15\Main.exe: *** Couldn't reserve space for
cygwin's heap (0x20030000) in child, cygheap, Win32 error 487
I tried two solutions posted in the mailing list for similiar problems:
first:
the "gcc -Wl,--heap,50000000,--stack,--50000000 ..." solution
here the simulation fails at small array sizes too.
second:
the "gcc -mno-cygwin ..." solution
here the program does start, but the only thing that happens is, if you
look in the task manager, the process slowly "collects" memory for about
90 seconds until it recaches 32MB (33xxxkB) and than the process crashes
with the windows message " the exception unknown software exception
(0xc00000fd) occured in the application at location 0x6104b9ef". During
that time the VM Size increases with the same rate, only it start at
values like 4xxMB or 6xxMB, depending on the array size (I have 1 GB RAM
so the pure size of these value isn't the real problem).
I think that the size of slightly below or even above 32MB is the cause
of the problem. Is there a general problem with cygwin and running
programs that require this amount of memory. Is there a way around this
problem.
Thanks for your help!
Regards,
Thorsten
