Hi Karim!

It would be easier for us to help you if you could post the source code.

I have a question, though:

When are you freeing the memory that is realloc()ed in MemoryFunction?
If this memory block is reallocated for each request, you will end up
using a lot of memory after a while if you don't free it.

However, we have had a problem with a memory leak in the IPV6 code. This is
believed to be fixed in the latest curl prerelease.
If you are using a machine with IPV6 enabled, you might want to try one
of these options:

1) Reconfigure your libcurl using ./configure --disable-ipv6

2) Download the latest prerelease and try it.

Please report if any of those alternatives solves your problem. We are
indeed interested if there is or was a memory leak in libcurl.

Regards,

Linus Nielsen Feltzing
