We are having a variety of issues with our cluster (2 node) abending at the moment, which I suspect is a backup express problem , However, a much more worrying / interesting fault occured on Sunday morning. No abend logs were captured, but the insight agents picked up the following

GWSMHNOV12 (master node)


ASR Lockup Detected: Code executing in module CIOS.NLM v1.60 at offset +8B1h when ASR NMI occurred.

GWSMHNOV11 (second node)

2:02 Abnoral Program Termination

Abnormal Program Termination (Abend: Deadlock waiting for spinlock currently owned by CPU 2 Running Process: DB Monitor EIP: 10B842h)

and both servers rebooted themselves.

Anyone have any ideas?
