I'm having some mysterious problems with the swap space on my onyx
system.
I'm running on an ONYX with 256M ram and 128M swap space in /dev/swap,
and 8, 200MHZ processors.
I've been trying to load in some fairly large .flt files.
When I load in too many tiles, and enter my pageDBase(), all the
processors spike out and eventually all the processes are killed off,
with the message that they've run out of swap space.
Makes sense to me.
If I query the system while my application is running, and ask it how
much swap space I'm using up, It usually gives me some piddly
number.(I'm using "swap -s")Typically just before crashing it will
tell me I'm using
9.33m of swap + 180.3m additional reserved = 189.63m total swap used,
with 170m of free swap remaining.
numbers here aren't exact, sometimes it uses more actual swap 30m or
less actual swap 0.0m
Thats real strange for me.
I've got another problem along these lines. I was trying to increase
my shared memory arena size to 512M in the hope that I could load in
more files. What happens is that it allocates the arena size, but
gives a SIGCHLD while loading in one of my files. Right now I can load
in 225 files. When I increase the arena size to 512M, it always bombs
on file 142.
I'm checking the shared arena size to see that it's changing to the
size I requested, and it is...
Any ideas would be greatly appreciated.
Jesse
