Dear Chris Costello,

    Thank you for the advice to ktrace to analyze my hung commands
passwd and send-pr.  

    Whoa!  There was a lot of output from kdump for my hung send-pr.
    I include here a shorter output from kdump for hung passwd:


   792 ktrace   RET   ktrace 0
   792 ktrace   CALL  readlink(0x280bcda4,0xefbfd4ec,0x3f)
   792 ktrace   NAMI  "/etc/malloc.conf"
   792 ktrace   RET   readlink -1 errno 2 No such file or directory
   792 ktrace   CALL  mmap(0,0x1000,0x3,0x1002,0xffffffff,0,0,0)
   792 ktrace   RET   mmap 671944704/0x280d1000
   792 ktrace   CALL  break(0x804c000)
   792 ktrace   RET   break 0
   792 ktrace   CALL  break(0x804d000)
   792 ktrace   RET   break 0
   792 ktrace   CALL  execve(0xefbfd5f4,0xefbfdab8,0xefbfdac0)
   792 ktrace   NAMI  "/home/wayne/passwd"
   792 ktrace   RET   execve -1 errno 2 No such file or directory
   792 ktrace   CALL  execve(0xefbfd5f4,0xefbfdab8,0xefbfdac0)
   792 ktrace   NAMI  "/bin/passwd"
   792 ktrace   RET   execve -1 errno 2 No such file or directory
   792 ktrace   CALL  execve(0xefbfd5f4,0xefbfdab8,0xefbfdac0)
   792 ktrace   NAMI  ".//passwd"
   792 ktrace   RET   execve -1 errno 2 No such file or directory
   792 ktrace   CALL  execve(0xefbfd5f4,0xefbfdab8,0xefbfdac0)
   792 ktrace   NAMI  "/usr/local/genome/bin/passwd"
   792 ktrace   RET   execve -1 errno 2 No such file or directory
   792 ktrace   CALL  execve(0xefbfd5f4,0xefbfdab8,0xefbfdac0)
   792 ktrace   NAMI  "/usr/bin/passwd"
   792 ktrace   NAMI  "/usr/libexec/ld-elf.so.1"

   This does nothing for me, although I can see that it is hunting
through my path for the program passwd, which it finds in its
proper place in /usr/bin.  
   Can anyone else find a solution here?
