system hang while using Gimp aggressively
I was working on some large (600dpi) images with lots of layers in the
Gimp, and had bumped up its image cache to 256MB to reduce
swapping. In the middle of a large copy, it froze x and, as far as I
could tell, the whole machine - it responded to pings but not
telnet. I left it overnight and came back the next day; it was still
hung. So I had to hard reset the machine, yuck.
What can cause this? It seems like simple out-of-memory etc. ought to
be caught by the system, and wabbits in my experience usually get
killed or die by themselves after awhile. I have a 1.4GHz athlon with
512MB of ram and 1GB of swap, running sid on 2.4.10 with JFS
patch. Here are some other pertinent facts:
