OpenDACS C++ API is crashing when using DACS sink daemon ms140 installation

Nicolas.Belhoste1

Hello,

We have upgraded the version DACS sink daemon to 7.7 ms140 version and we got a crash when running our connector.

I noticed that in the sink daemon package the version of dacs4wn64.dll is in 7.10.0.1.

Our connector is using OpenDACS v8.2.0.L2 version (DACS8_lib140_x64.dll is in 8.2.0.2) where dacs4wn64.dll is 7.7.0.1.

The weird thing is that we get not crash when using ms100 version.

Here is the call stack of the crash :

Exception thrown: read access violation.

tmp_uint16 was 0x8E51846A.

Any idea about this issue?

Thank you for reaching out to us.

I think you need to use the dacs4wn64.dll which is in the OpenDACS package.

You should not use the newer version of that DLL that is in the DACS package because the API may not be tested with the newer version.
