Hello everbody,
we currently investigate an issue regarding services/applications which crashing with internal .net error
The process was terminated due to an internal error in the .NET Runtime at IP 00007FFAD128A48F (00007FFAD0EA0000) with exit code 80131506.
Using Paged Heap Verfication and Analyzing serveral dumps, it seems that the GC causes that issue, if it runs on gcServer mode. This only happens since we update .net to 4.5 on that virtual maschine and it only occurs if the memory of the VM is 64 GB (which is used by the crashing service/application up to 90%).
We can produce the same error with a real simply .net application and it only occurs with gcServer (gcConcurrent is independet). As the crash can only reproduce on high memory VMs (meaning not on small memory VM - 10 GB - and not on real hardware up to 64 GB). We want to ask if this is maybe a Hyper-V issue, and is maybe allready known and can be fixed. In the past, that crash sometimes causes also a restart of the whole VM.
Thanks for your support!
