Giulio, it seems this is anyhow not related to network (nfs) operations. It's looking like a problem in the VM. I think it makes sense to have a look at the httpd.core file if the binary has been linked with debugging symbols turned on. Also I think at first, it may not hurt to look at vmstat -m output. You may want to change ${subject} and post to stable@ to drive more attention to your problem. Volker
