[Quickfix-users] Memory Leak - Please help.

[Sam S. <sa...@if...>]

Hi,

 

I am reasonably new to QuickFix and I have a problem. I have been asked
to look at part of a C# application using the .Net QuickFixEngine
library.

 

My problem is that the application seems to have substantial memory
leak.

 

Looking at the application using a .Net memory profiler, it looks like a
lot of QuickFix objects are hanging around in memory. It looks like the
.Net code is releasing all references to the objects, but some unmanaged
code is retaining a reference.

 

Am I missing something obvious? Should the developers who wrote it have
been calling a .Dispose method or delete or something on these objects?
One major source of the leak seems to come from messages that are
created by the unmanaged C++ library and passed into our managed code.
When our managed code finishes with them they do not seem to get cleaned
up.

 

Please help.
