What do you mean "didn't reproduced"?

Is it with  the same unpatched tsp-0.8.3 or with the patched version
provided by Fred?

As a complementary question
do you run several blackboard and/or TSP provider on the same host?
If yes are they run by the same user and/or not?

Fred do you have time to investigate that?

Yes you should debug this either using STRACE_DEBUG env var and/or a debugger.

if you set

export STRACE_DEBUG=3 in the terminal where you launch
tsp_bb_provider and/or tsp_stdout_client
you'll get trace of tsp library actions which may give us (or you)
more informations.

*BEFORE* launching tsp_stdout_client could you play around with

tsp_request_generic client.

tsp_request_generic --help for mmore information or see
http://nongnu.mirror.ironie.org/releases/tsp/documentations/tsp_programming_guide-1.1.pdf
(§ 11.2.1)

Does the lockup occurs with other client (i.e. targa)
