Fatal error: out of memory

Fatal error: out of memory

[Sarah DJEBALI]

Hi,

I am using ocaml 3.08, and when running my executable on certain kind of 
data I get the message :
Fatal error: out of memory.

To diagnose the problem and as adviced in the user manual,  I have run 
ocamlrun with the option -v.
It displays lots of "growing heap..." messages with the heap size 
growing slowly.
In such situations the user manual says there is an attempt to construct 
a data structure with too many cells.

I know this may look a very naive question,
but is is possible to increase the heap size?

Thank you in advance
Sarah

Can you please try with 3.09 in experimental ?

Well, usually you get this behavior because your application is not written
optimally, especially with recursive functions.

Probably, but not sure it will solve your problem. There is an ocaml-beginner
mailing list somewhere which would be more appropriate though, as here we
usually deal with packaging issues mostly.

Oh, well, i messed up the mailing list, sorry about that, please ignore my
debian related comments.

Still the beginner list above may be more appropriate, not sure if you where
there before.

The heap size increases automatically until your OS refuses to  
allocate more
memory to your program, then you get the "out of memory" message.

Your program is probably trying to build a data structure that is too  
big for
your computer.
