FileMaker Server is crashing randomly. We're using FileMaker Server since 2016 and this crash occured 70 times since then.
I have attached some crash dump analysis output done with WinDbg. It shows that the crash occurs in FMFileTransferWebServicesClient with a primary problem class "NULL_CLASS_PTR_DEREFERENCE", located in DBEngine.dll.
How to replicate:
Sadly, we haven't found a way to reproduce the problem, as it occurs "radonmly" to us.
