[Valgrind-users] Valgrind with linux daemon

[sankoor s. <sam...@ya...>]

Hi,

Am very new valgrind, pl help me out:
I have daemon running on linux machine, in which i have injected 1MB memory leak & trying to find memory leak in a daemon using valgrind.
But am not able to get the proper memory leak ouptut , Pl find the below the valgrind o/p:
/usr/bin/valgrind --tool=memcheck --num-callers=8 --leak-check=full --leak-resolution=high --error-limit=no --show-reachable=yes --track-origins=yes startsrc -s FSRM
