 It mounts different file systems by NFS (with locking) on a
 data server directly connected (gigabit) to the server

 Apache running in a several jails on those nfs folders.

 Now and then I get huge slow-down. When I look in the logs
 I get thousand of lines like these:
 Mar  5 11:50:52 virt2 kernel: vm_fault: pager read error, pid 46487 (httpd)
 Mar  5 11:50:52 virt2 kernel: pid 46487 (httpd), uid 80: exited on
 signal 11


 What should I do?

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
