Problems on setuid solaris file


Hi all,
I got some problems to debug setuid file on solaris system. Currently I got the same problem on solaris 8 and 9.
The test are did with GDB 6.0 (the same with prior) and gcc 3.3.2 and gcc 3.2.


(gdb) r
Starting program: /export/home/inode/test
procfs: target_wait (wait_for_stop) line 3931, /proc/11035: Resource temporarily unavailable.
(gdb)


Anyone have idea?

Thanks in advance

Inode_
