We have updated from 5.4 -> 6.0 -> 6.2 -> 7.0 all have had no effect on the lockups which happen when the stats run. This box is also on an areca controller but it was on an Adaptec and we saw pretty much the same thing so I suspect its not related to the controller more to the way things are read from and flushed to disk. When we see this problem any ssh sessions become totally unresponsive. The stats we are running are a combination of rrdtool updates from a mysql DB and rrdtool backed mrtg for network stats. This is very reproducible here as it "stalls" the box every few mins when the stats kick off so if there needs to be more investigation we should be able to help.
