[GRASS-user] Error while converting reclassed raster to vector

Greetings
I’m converting a reclasses raster (produced with r.reclass) to a vector (areas, not lines neither points) but I got this weird error:
ERROR: G_realloc: unable to allocate 24632000 bytes at areas.c:678
What does this mean?

Thanks
Franz

you are allocate 24Gb of memory, check out your computational region

g.region rast=raster_map
r.to.vect ...

Hi Martin
I have done exacly that (the g.region stuff)
I believe my region is not so big.
Resolution:300
rows:5381
cols:4481

Any more tips on this?
Franz
