What's the load on the box when those results get sent ? How many bbd
processes are running ? Try running a "vmstat 2 300" and watch the 
usr/sys/idle cpu-time distribution and the I/O activity.

bbtest-net dumps a lot of results to the bbd daemon, very
rapidly. This means the bbd daemon forks a lot of child processes, one
to handle each message. If you have some tests that have failed, this
will trigger "page" messages which means even more processes that
start up. 

Since you mentioned that the box doesn't have plenty of memory to
spare, I suspect that your box simply runs out of memory when all of
those messages hit it at once, and then everything slows down.

Does it help if you set BBSLEEPBETWEENMSGS=1000000 in bbsys.local and
restart Hobbit ? This adds a 1000000 microsecs (ie. 1 second) delay
between each combo-message that is sent.
