Hi altogether,

my laptop runs under linux debian 10 and has 8 GB RAM. Edit  › Options  ›
Memory & Threads does not allow me to increase the value above 2666MB.

relevant lines in /usr/bin/imagej (a not so simple wrapper script used to
run ImageJ) are

declare -i mem
declare -i default_mem=4000
declare -i min_mem=16
declare -i max_mem
declare -i free_mem

and further down

elif [[ `uname` == 'Linux' ]] ; then
    if [[ `uname -m` == 'x86_64' ]] ; then
        java_path="${ij_path}/jre64/bin/java"
        max_mem=`free | awk 'NR == 2 {fmem=int($2 / 1024); if (fmem < 4000)
{print fmem} else {print 4000}}'`
        free_mem=`free | awk 'NR == 3 {fmem=int($4 / 1024); if (fmem <
4000) {print fmem} else {print 4000}}'`
        mem=${free_mem}/3*2
        if (( $mem > $default_mem || $mem < $min_mem )) ; then
mem=$default_mem ; fi
    else

typing free:
              total        used        free      shared  buff/cache
available
Mem:        8064332     1579956     2659136      183288     3825240
5998348
Swap:       8282108           0     8282108

changing declare -i default_mem=4000 to declare -i default_mem=8000 has no
effect on the lines further down

where is the superior position where the change to 8000 makes a difference
in the file imagej?

thank you, Thomas
