The reson why and solution
 o maybe the ptys are all in used indeed.
   ==> change the kernel config file
       change the following line
>pseudo-device pty # pseudo-tty's, also needed for SunView
       to things like
>pseudo-device pty128 # pseudo-tty's, also needed for SunView
       ( default is 48 )
       then re-make the kernel,
       and make pseduo devices for ptys in /dev if you want to use
       more than 64 ptys ( the default for /dev )
  o maybe some process remain occupies some ptys though "ps -aux"
       doesn't show their control terminal, use "fuser", or get utility like "ofiles"
       ( use "archie" to find it ) to check the ptys that can't be allocated by
