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.
