Get a quick question about segmentation faults that looks like
memory startvation.


Running a kernel with the following


include	"std.i386"

maxusers	256			# automatic parameter tuning
timezone	0			# use GMT in hardware clock

options 	KTRACE			# syscall tracing
options 	COMPAT_BSDI11		# compat with BSD/OS 1.1 binaries
options 	COMPAT_TTYIOCTL		# old tty interface, many progs need
options 	COMPAT_SEMAPHORE	# for pre-3.0 -lipc/SCO emulator only
options 	COFF			# COFF executables, for SCO emulator

options 	FPE			# floating point emulation
					# (also settable with sysctl)


# network options
options 	INET			# Internet: TCP/IP
options 	GATEWAY			# IP routing
options 	"IPFORWARDSRCRT=0"	# disable forwarding of src-routed pkts

# Support for large inpcb hash tables, e.g. busy WEB servers.
options 	INET_SERVER

options 	INET6			# IPv6

options 	IPSEC_ESP		# IP encryption

# Support for more than 1G of physical memory.  For up to this
# much memory:		1.75G	2.5G	3.25G	4G
# use this value:	376	504	760	1016
options 	"KERNEL_VIRTUAL_MB=1016"

# Support for large routing tables, e.g. gated with full Internet
# routing.  Make sure you have more physical memory than this.

So why is perl segfault, apaceh giving me next to midnight 1 Jan 1970
dates in its log as well as sshd should 1 Jan 1970 dates.

Also freshclam, a clamav updater is choking.
