yes, everything is working fine at the moment. I still donít know why this 503s occurred, though. As a too high memory consumption would only cause a recycle my guess was that DNN is using too much CPU time. However, your logs show nothing so thatís quite strange.
Well, Iíve created a Scheduled Task to check for 503s and if this will happen again maybe Iíll change the CMS to Orchard or MojoPortal or something like that.
