Plesk 7.5 + RHES: Several domains just died..
Overnight, 7 domains (on different accounts) just died, stopped working. They cannot be pinged, obviously can't be accessed by any browsers, and just don't respond at all.I rebooted the box, and individually restarted apache and bind to no avail. It seems awfully strange, no DNS issues, and all different accounts. However, on the same box, all the other domains are working fine.
They're not over any limits, and show fine in Plesk.
Any ideas?
