The LCS Crash and Hang analysis feature, which allowed automated analysis of DMP files collected from AX 2012, is being discontinued.
Following recent improvements in our cloud infrastructure, the mechanism that enabled the automated analysis of DMP logs is no longer compatible and will not be supported anymore.
As an alternative, we have published an article describing how DMP files can be analysed manually using debugging tools and the LCS issue search: Extracting Information from Crash and Hang Dumps.
If a more in-depth analysis is required, Microsoft Support remains prepared to assist you.
