We are on 3.8.1 AIX 5.1 with an EMC san and have seen the same thing. In fact I ran the engine for an entire day that way 2 months ago. I don’t believe the recovery writes are commited. But both you and I have enough memory to handle msgs going through without swaping to disk – which saved me some down time.
In these cases (I’ve had a couple), The smat files are never created and each process directory has contained a number of 0 byte thread files that I needed to clean up once the san was connected.
I was amazed, and happy, that the engine continued to run throughout the weekday without disk – that, to me, seemed to be a benefit rather than a drawback.
