Totally hosed up filesystem..wtf?

[Jeff Mohler]

So..last night im workin away, and then the machine gets slow, then
stops responding to anything.

I can ping it, but no telnet, www...anything.  Hung hard.  Last thing
I saw in a make buildworld was a 'cant write to filesystem' error..or
something like that but not a 'no room on device' error.

Have my remote helper power cycle it, as he cant get in either.

Comes up asking for single user shell, get in, and fsck -y fails with:

fsck_ufs: cannot alloc [random # of bytes here]

Searching tells me in dead.

Running 6.1.


Help??
