Hello Dlubal Community,
our RFEMServer instance running on a Windows Server experiences crashes quite often. From the logs, it is apparent that the crash is related to the CrashReportEngine, but the details are not understandable for a layman like me.
Here is an excerpt from the logs:

CRASH_REPORT_WAS_NOT_SENT
I could not find any entry regarding this in the RFEM Release Notes, so I assume the error still exists and an update of RFEM does not make sense yet.
I am happy to provide the complete logs if needed.
