These are the Streams daemons starting up. They are created the first 
time that a pipe or fifo is opened not necessarily when the first Posix 
thing is done, i.e.

shell/iX> cat foo | grep bar

One way they start immediately after booting is when the Predictive 
JPSMON job runs, it does something with a pipe or fifo to cause them to 
start.
