Memory leak referencing .net dll

My Virtual Memory gets about 8k higher every minute.

My Physical Memory about 4K every minute.

Is the problem in the external dll or in the c++ code?

Hello,

I have written the same code in c# and i seem to have any problems?

I use 'procexp.exe' to check the performance.

In the case of 'c++' the VM (Virtual Memory) and PM (Physical Memory) becomes larger every minute.

There is also an I/O block with a lot of parameters :-)

In c# only the parameter 'other' gets larger, the other parameters stay the same.

In c++ all the parameters change?!
