libc raises exception when it detects memory violation.

You can probably try to use valgrind to identify memory leak in
xenconsoled.


Wei.

Feeling in a little over my head now,

I have run valgrind and include the file with the output. As before xenconsoled crashes, but i am not really sure how to read what i am seeing from valgrind. I am not really sure if it is telling me that these errors happen as it goes along, or if it is as a result of the crash that there are lost blocks around.

Valgrind was run with:

valgrind --tool=memcheck --leak-check=yes --show-reachable=yes --num-callers=20 --log-file="valgrind_output.txt" --track-fds=yes ./xenconsoled --pid-file=/var/run/xenconsoled.pid

If the attached file doesn't show, could you tell where it should go?

Paul
