Thanks to everyone so far.
However, setting ulimit to unlimited does not seem to solve the
issue. Output from ulimit -a is:
truffula:~ kwythers$ ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
file size (blocks, -f) unlimited
max locked memory (kbytes, -l) unlimited
max memory size (kbytes, -m) unlimited
open files (-n) 256
pipe size (512 bytes, -p) 1
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 100
virtual memory (kbytes, -v) unlimited
Also, changes to kernel settings in /etc/rc include:
sysctl -w kern.sysv.shmmax=167772160
sysctl -w kern.sysv.shmmin=1
sysctl -w kern.sysv.shmmni=32
sysctl -w kern.sysv.shmseg=8
sysctl -w kern.sysv.shmall=65536
However, I'm still getting the memory error:
met_data=# SELECT sites.station_id, sites.longname, sites.lat,
sites.lon, sites.thepoint_meter, weather.date, weather.year,
weather.month, weather.day, weather.doy, weather.precip,
weather.tmin, weather.tmax, weather.snowfall, weather.snowdepth,
weather.tmean FROM sites LEFT OUTER JOIN weather ON sites.station_id
= weather.station_id;
psql(532) malloc: *** vm_allocate(size=8421376) failed (error code=3)
psql(532) malloc: *** error: can't allocate region
psql(532) malloc: *** set a breakpoint in szone_error to debug
out of memory for query result
Any other ideas out there?
