Hey Nic,
You shouldn't worry, no discrepancy exists unless you purposefully create it.
All CP servers (GW/Mgmt/Log-Server/SME, etc...) use & apply the log disk-space maintenance policy from/to this file:
$MDS_FWDIR/conf/log_policy.C
If you change it manually & run a restart to FWD process (cprestart), then your changes will now take hold temporarily, till an install database occurs, which will override your manual settings, so the GUI settings will again override the file & take hold.
but I must stress that there is no need to modify it manually aside from specific scenarios, like a Global SmartEvent server.
