That's cute - does it beep? page you?

Crash, could be due to resource exhaustion, or some filesystem backup
utility locking blocks of disk so the server can't access
them. (Online databases must be excluded from system backups!)

...or, rather, not disconnecting at all. When you say "nobody is
using the system", what means do you use to test that users are not
connected before you shut down the server?

...are you sure that the busy night-work is not
garbage-collection? Do you watch the stats at all to get an idea of
what to expect when idle time is available?

...do any of your applications use events?

...is some kind of filesystem backup being done over the top of
connected databases?

That's more than a year and a half old and 2 sub-releases
behind. Have you checked the v.1.5.2 and v.1.5.3 bugfixes in the
latest (1.5.3) release notes to see whether there are any fixes there
for problems similar to yours?
