I threw an "echo phpinfo()" into the importImages.php script and got:
memory_limit => 64M => 32M
So I wonder if there's another memory limit imposed by jailshell along the lines of
"ulimit"? ulimit -a says:
core file size (blocks, -c) 200000
data seg size (kbytes, -d) 200000
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 73728
max locked memory (kbytes, -l) 32
max memory size (kbytes, -m) 200000
open files (-n) 100
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 20
virtual memory (kbytes, -v) 200000
file locks (-x) unlimited
