VDDK crash dumps might be missing on Windows machines

Products

• VMware Aria Suite

Issue/Introduction

This article helps customers deal with unknown VDDK failures by enabling them to produce

core dumps that may be useful for troubleshooting and diagnosis.

Symptoms:

When a VDDK application fails on a Windows machine while running vmacore library code,

no crash dump is generated.

Cause

VDDK runs code and creates threads from vmacore.dll, which has its own exception handler.

If a crash occurs in these threads, the core dump file is generated by vmacore.dll

in a hard-coded folder location, C:\Users\<UserName>\AppData\Local\VMware.

If this folder does not exist, vmacore skips generating a crash dump.

Resolution

None currently. A fix has been identified and will be available in a future release.

Workaround:

None currently. A fix has been identified and will be available in a future release.
