Corrupted memory and/or user-mode code dumps on Azure Gateways and OCI Technical Level
Symptoms
  • Corrupted HKLM_registry.data file.
  • Large amount of usermode core files on the system.
Cause

The selected Azure image size D2v2 (Ds2v2) is a 2 core image size, which means that the fw_workers and SNDs share the same resources. As a result, there are cases in which the resources are not properly released and cause some processes to core dump.

The fwmultik_sync_processing_enabled (synchronous dequeue feature) kernel parameter is enabled. This limits the CPU to handle fewer stack functions simultaneously.
