For the past 8 weeks or so, our NW server 6.5 has started to abend/hang at least once a week if not more often. It mostly abends on Sunday mornings. I have attached the full abend log from the lastest abends. I've simply been restarting the server which is all we can do at this point but would like some assistance in figuring out the underlying cause. It looks like it has something to do with gwia.
