Посмотрите, ограничивает ли это максимум времени выполнения:
[wally@zf conf]$ ulimit -all
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 16114
max locked memory (kbytes, -l) 32
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 10240
cpu time (seconds, -t) unlimited
max user processes (-u) 16114
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
Обратите внимание, что размер стека по умолчанию ограничен 10 МБ. Таким образом, чтобы увеличить его до 64 МиБ:
[wally@zf conf]$ ulimit -s 64M
-bash: ulimit: 64M: invalid number
[wally@zf conf]$ ulimit -s 65536
[wally@zf conf]$ ulimit -all
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
