From within the thread itself, I suppose I can fork1() to duplicate the
thread and fork another process to run pstack on the duplicated thread.
I would much rather use some api to print out the stack directly. Any
pointer would be appreciated.

1. demystifying process stack vs. java thread stack on solaris
I am having a very difficult time finding information related to
process stack size, java thread stack size and how these are combined
to affect process memory limits on Solaris. Basically I would like to
put some science to tuning the jvm on solaris for a large number of
concurrent threads. Currently I am running into Java out of memory
errors when the heap has plenty of room to grow. I suspect that the
issue is related to total process memory and how the thread stack
sizes are combined with the maximum heap allocation. The two knobs I
know of to affect process stack and thread stacks are 'ulimit -s' for
process stack and '-Xss' for java thread stacks.
How do these settings affect each other?
Solaris:
Solaris 9 12/02 s9s_u2wos_10a SPARC
Java:
Java HotSpot(TM) Client VM (build 1.4.1_02-b06, mixed mode)
Java Command Line Switches:
-server -Xms256m -Xmx3072m
ulimit output:
$ ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) unlimited
stack(kbytes) 32784
coredump(blocks) unlimited
nofiles(descriptors) 40000
vmemory(kbytes) unlimited
