Hi,

I'm quite sure that this is not a bug, but -- as has been noted in the
answer to your stackoverflow question -- your system simply runs out of
memory and the "OOM killer" terminates your process. I tried your PDF
conversion example and it has a peak memory usage around 2.5GB -- how
much physical RAM and swap does your system have? In case your process
is killed for this reason, there should be a log entry in
/var/log/syslog or /var/log/kern.log . Note that some computation code
does not use the peak memory during its computations but in the end when
all the results are saved to disk. In case you are really sure that your
memory size is sufficient, please also try to run memtest -- maybe some
of your RAM is defect (even though this should rather lead to random
errors instead of the termination by the operating system).
