Not really a Linux problem but Dell h/w. They constantly change specs and seem to not have the quality under heavy load. Dell is built on just enough. We have smoked three of their top of the line servers with actual smoke coming out of them. For years now we simply do not support Dell h/w in a server environment. Not to say they are all bad, but too many issues which are not there with for example Supermicro. So in the long run we've not found it viable to support them at all. -- Bobby
