we add the nmon commond in crontab for OS, every day get one file.

0 0 * * * /usr/bin/nmon -fT -m /home/nmon_monitor -s 120 -c 719 > /dev/null 2>&1

Hi,
What happens when you run that command from the command lline?
What happens if you run nmon onscree? i.e. just type: /usr/bin/nmon
What version of nmon is this? Use: nmon -V
If it is not nmon 16f please upgrade.
What Linux and platform are you running? Output from: cat /etc/*ease.
Is this the only problem machine of dozens or is this you first attempt?
Is /usr/bin/nmon a script or is that a binar? The log thinks it is nmon_x86_64_rhe

Cheers, Nigel

thanks very much.

1. the OS is redhat 6.4.
2. the file is nmon_x86_64_rhel6.
3. the version is 14g
4. we add the crontab for this nmon for 3years and is ok always.
5. only Apr 18 22:00 to 23:59 is stop or error. after Apr 29 00:00 the nmon is normally by itself.
6. the crontab I post may be is wrong. the correct is as follows:
   0 0 * * * /usr/bin/nmon_x86_64_rhel6 -ft -s 120 -c 719 -m /home/omc/nmon > /dev/null 2>&1

nmon 14g !!!!!
You are 2 years, missing many bug fixes and a dozen release behind 16f.
I am not going to debug ancient history for you.
PLEASE UPGRADE
and Retry.

Thank you very very much.
I am very happy to received your reply. I am so excited.
I have download this version file. because our OS is redhat 6.4 for X86.
May be this is the latest file for our OS.

I have the same exact issue...although I am running RHEL 6.1 and nmon 16d :(
YES of course I want to upgrade both. Weird thing is that I have some systems with same versions that work fine, but others that don't.
