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.
