I can't get a thread dump.
ps -3 <pid> give me this:
diamond (devsas1)$ps -lf 20758
usage: ps [ -aAdeflcjLPyZ ] [ -o format ] [ -t termlist ]
[ -u userlist ] [ -U userlist ] [ -G grouplist ]
[ -p proclist ] [ -g pgrplist ] [ -s sidlist ] [ -z zonelist ]
'format' is one or more of:
user ruser group rgroup uid ruid gid rgid pid ppid pgid sid taskid ctid
pri opri pcpu pmem vsz rss osz nice class time etime stime zone zoneid
f s c lwp nlwp psr tty addr wchan fname comm args projid project pset
