Hi,

We tries shifting our mail delivery to the NAS and the load on the exim server just kept going up. According to the exim info I have found on the web this is due to IO wait, problems.

We stopped the mail server at this point and exim could not end the processes running trying to deliver to the nas, and we had to reboot the machine to clear these out. We also tries this from another machine (redhat 7.3) and had the same problems.

When I set up an nfs share on a linux box (RedHat Enterprise 4) to do the same thing we had no such problems.

Have you any idea of what may be going wrong? The server is catering for 4000 - 5000 mailboxes.

Regards

Andy
