Site Preview times out

[vnchristina]

This problem seems to be happening periodically on my Debian etch server. First with 9.0.0 and now with 9.0.1. All sites on the server just time out when trying to preview them. I've considered upgrading to 9.2, but and worried it will just cause more problems. The logs are lacking in useful errors. Is anyone else experiencing a similar problem or know how to fix this?

In case anyone else has had the same problem, it appears to be related to the loopback entry. In this case, it was missing. For some reason when I reboot the machine, it gets removed. Anyway, after adding it, site preview works again.
