Linker options when perl is built:

perl -V |grep maxdata
ld='ld', ldflags =' -brtl -b32 -bmaxdata:0x80000000'

Maybe there is a 64-bit build of perl for AIX?

My perl installation was compiled with the same maxdata value as you
specified above, even 64 bit binaries...

# perl -V | grep maxdata
ld='ld', ldflags ='-brtl -bmaxdata:0x80000000 -q64 -b64'

0x80000000 == 2147483648 == 2097152 kbytes...

I know what i have to do...

Thanks

I'm against unlimited ulimit settings - it's just as bad as running
third party applications as root. Limits provide a last resort safety
net that should just not be removed.

Nothing wrong with just incrementing maxdata for perl:

ldedit -b maxdata:0xA0000000 perl

but I'd never use unlimited data, stack and memory settings for any user
even if I have take the time to calculate a sane limit as a percentage
of realmem.
