Hi,

May be not directly related to concurrency. But here is my question:

What is the default size of the Thread Stack and Thead Local Data. Does it depend on OS? When I did ulimit command on my server I see stack size. Does this related to Thread Stack in Java.


 
ulimit -a

core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 532480


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) 532480
virtual memory          (kbytes, -v) unlimited


file locks                      (-x) unlimited

Regards,
Ramesh
