Hi, Comments prefixed with [PS] below.

Returns 1 after the 3rd command. Does running ndmpd "by hand" work as the third step? 3. /usr/local/ndmp/ndmpd & # start in background, note the PID 4. ps -ef # does ndmpd show with the same PID as given by the shell? [PS] In step 3, the process, if run by hand (/usr/local/ndmp/ndmpd &) exits immideiately. If "service ndmpd start" does anything other than execute /usr/local/ndmp/ndmpd, then it may be necessary to add a level of indirection through a shell script that runs valgrind: 1. service ndmpd stop 2. mv /usr/local/ndmp/ndmpd /usr/local/ndmp/ndmpd.real 3. cat >/usr/local/ndmp/ndmpd <<!EOF! #!/bin/bash exec valgrind -v --num-callers=50 --log-file=ndmp_valgrind_30_8.log --leak-check=full /usr/local/ndmp/ndmpd.real !EOF! 4. chmod +x /usr/local/ndmp/ndmpd 5. service ndmpd start [PS] service ndmpd start FAILS to run using a wrapper. $ service ndmpd stop Stopping ndmpd: [ OK ] $ service ndmpd start Starting ndmpd: [FAILED] $ cat /usr/local/ndmp/ndmpd #!/bin/bash #/usr/local/ndmp/ndmpd.real exec valgrind -v --num-callers=50 --log-file=ndmp_valgrind_04_09.log --leak-check=full /usr/local/ndmp/ndmpd.real $ ps -ef | grep valgrind root 22481 1 0 11:38 ? 00:00:00 valgrind -v --num-callers=50 --log-file=ndmp_valgrind_04_09.log --leak-check=full /usr/local/ndmp/ndmpd.real root 23269 4513 0 11:42 pts/4 00:00:00 grep --color=auto valgrind $ ps -ef | grep ndmpd root 22481 1 0 11:38 ? 00:00:00 valgrind -v --num-callers=50 --log-file=ndmp_valgrind_04_09.log --leak-check=full /usr/local/ndmp/ndmpd.real root 23309 4513 0 11:42 pts/4 00:00:00 grep --color=auto ndmpd As per our observation ndmp internally starts session monitor. But in this case we were not able to see the session monitor and ndmp. Is there any other way to run valgrind on ndmp ?
