Hi,

I have a problem cancelling threads with pthread_cancel under Linux.
The logic is the following: Start a few threads in a mother thread
which read different device files. The thread which finnishes first
will cancel all sister threads. The mother thread joins all sister
threads and repeats the whole procedure.

This works without problems for a while, but after some time (in which
the program does not need to run) it is not possible to cancel sister
threads anymore and pthread_cancel is returning "resource temporarily
unavailable" when the program is run the next time.

I thought I had solved all memory problems, but now I'm wondering
whether the error is produced by a memory leak or is a problem with
threads in Linux. Anyway, I would be happy, if anyone can tell me
under which conditions the "resource temporarily unavailable"-error is
produced.


Thanks,

Sebastian
