This message means that the Netapp server is replying EACCES to a read for a pagein. I notice that both root and www are running the executable. (Also, root is often mapped to something like "nobody" in the NFS server.) You could try making sure the httpd executable file has r_x permissions for all users (chmod 555 httpd). If it still keeps hapenning once you've done that, you'd need to capture packets when this happens and take a look at the NFS RPCs via wireshark to see when the EACCES is returned and what <uid, gids> are sent in the credentials for that Read. rick > errors on my screen =E2=80=A6 not always same pid =E2=80=A6 the annoying = part is that > it seems to always affect the same jail that is running .. if I > shutdown all jails on that physical server, everything shuts down > except for that *one* jail, with a ps listing looking like: >=20 > USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND > root 6670 0.0 0.0 9936 1372 ??
