The ncargs value determines the ARG/ENV list size in 4K byte blocks.

Check with

lsattr -El sys0 -a ncargs -F value

Default is 6 (AIX 5) resp. 256 (AIX 6/7), the allowable range is from 6 to 1024 (AIX 5) resp. from 256 to 1024 (AIX 6/7)

Set with

chdev -l sys0 -a ncargs=new_value

ncargs can be raised to keep programs from failing with the arg list too long error message.
