Interesting... I just got another hard lock on the system, not at 3am
this time. The only other common factor in this is that the lockup
is always preceeded by a flood of failed ssh logins. I;m sure we've
all seen these - I get them on every BSD system I have - they look
like this:

Dec 22 17:37:10 turpentine sshd[8188]: error: PAM: authentication error for illegal user kevin from 61.74.75.43
Dec 22 17:43:21 turpentine sshd[9983]: error: PAM: authentication error for illegal user kevin from 58.60.106.24
Dec 22 17:49:30 turpentine sshd[11781]: error: PAM: authentication error for illegal user kevin from 219.234.95.164
Dec 22 18:01:47 turpentine sshd[15435]: error: PAM: authentication error for illegal user kevin from 61.74.75.43
Dec 22 18:07:54 turpentine sshd[17259]: error: PAM: authentication error for illegal user kevin from 61.74.75.43
Dec 22 18:14:06 turpentine sshd[19282]: error: PAM: authentication error for illegal user kevin from 61.74.75.53

Theres always a flood of those on the console immediately preceeding
the lockup. So this time it cant have been anything to do with the
3am run.

-pete.
