Freebsd 8 stable amd64

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?
