Graphics, Figures & Tables ⇒ TeX capacity exceeded, sorry [pool size=1151122]

[ashish]

When using the PSTricks fileplot command, I was getting the error:
TeX capacity exceeded, sorry [main memory size=3000000]

After some searching, I found out I can fix this by modifying the file returned by:
$ kpsewhich texmf.cnf
/usr/local/texlive/2008/texmf.cnf

I added the line:
main_memory = 10000000

and then ran:
$ sudo fmtutil-sys --all

This seems to have fixed the main memory size problem, but now I'm getting the error:
TeX capacity exceeded, sorry [pool size=1151122]

I tried the same procedure, and added the line:
pool = 2151122

But it does not seem to have any effect. I also tried pool_size = 2151122. Does anyone know how to set the pool size to a higher limit. Thank you.
