Hello,
OS = Tru64 V5.1A
One of the user got an error message during the execution of a program:
stack overflow
.
.
Core dumped.
The present configuration:
sysconfig -q proc output
$sysconfig -q proc
proc:
max_proc_per_user = 256
max_threads_per_user = 1024
per_proc_stack_size = 4194304 <-------------------
max_per_proc_stack_size = 48000000 <---------------------
per_proc_data_size = 2147483648
max_per_proc_data_size = 2147483648
max_per_proc_address_space = 2147483648
per_proc_address_space = 2147483648
executable_stack = 0
autonice = 0
autonice_time = 600
autonice_penalty = 4
open_max_soft = 4096
open_max_hard = 4096
ncallout_alloc_size = 8192
round_robin_switch_rate = 0
sched_min_idle = 0
give_boost = 1
maxusers = 2048
num_wait_queues = 2048
num_timeout_hash_queues = 2048
enhanced_core_name = 0
enhanced_core_max_versions = 16
exec_disable_arg_limit = 0
dump_cores = 1
dump_setugid_cores = 0
limit output:
=============
$limit
cputime unlimited
filesize unlimited
datasize 2097152 kbytes
stacksize 46875 kbytes
coredumpsize unlimited
memoryuse 3068192 kbytes
vmemoryuse 2097152 kbytes
descriptors 4096
Can I just increase the process stack values(proc stack and max stack)
without increasing the other values? What is the maximum size I can
define
for stack in a 3G memory machine?
Thanks in advance,
Kumar
