Updated by Could you run tvh under valgrind ? It seems that this is a consequence of something else.

ok - will try valgrind
Updated by Jaroslav Kysela over 8 years ago
It seems like a memory corruption. Valgrind might detect the wrong memory access.
Updated by Thomas Smith over 8 years ago
starting valgrind in a screen-session and waiting for crash:
valgrind --leak-check=full --show-reachable=yes /home/hts/case-xxxx/tvheadend/build.linux/tvheadend -D
some output:

i dont know why, but valgrind doesnt work on my nas (with a putty-session or in a screen-session)
after starting tvh in valgrind, webserver is working :9981 but when i start a htsp-stream, tvh crashes immediatly
in my opinion, my nas is too weak for valgrind
any other possibilities to find the problem?
