OBSD 2.3/pmax (-current): vm_fork: no more kernel virtual memory

[Nino Margetic <nino_(_at_)_well_(_dot_)_ox_(_dot_)_ac_(_dot_)_uk>]

Dear all,

I was wondering if anyone can advise how to avoid panics due to the above
message. My -current is a week old snapshot.

Machine is used at home as a semi-development system (semi due to lack of
gdb :-). It is running sendmail, dhcpd, sshd, smbd, nmbd.

I have attached at the bottom my kernel config file and dmesg output. Let
it be noted that I am mounting swap onto /tmp.

Thanks,

--Nino
