Hi.

Using pstack I can get full stack, using ustack() all I see is last stacked
function.
bash-3.00# dtrace -w -n syscall::read:entry''/execname ==
"wp-smtpd" && fds[arg0].fi_pathname ==
"/opt/zones/smtp/root/dev/urandom"/{ustack();trace(pid);stop();exit(0);}''
dtrace: description ''syscall::read:entry'' matched 1 probe
dtrace: allowing destructive actions
CPU ID FUNCTION:NAME
1 10 read:entry
libc.so.1`_read+0x15
6504
bash-3.00# pstack 6504
6504: /opt/WP/WP-XXX/bin/wp-smtpd
ce470c05 _read (3, 804787c, 20) + 15
ce5866f9 RAND_poll () + 172
