Can't stop SpamAssassin; it appears to restart itself (or green indicators wrong?)

[dotchd]

My system: Parallels Plesk Panel v11.0.9_build110120608.16 / CentOS 6.2 (Final)

I need help stopping SpamAssassin. Each time I disable SpamAssassin through SSH with "#service psa-spamassassin stop " or through the panel (Tools & Settings > Services management) the green indicators turn grey in the panel as well in my mobile Plesk server monitor app for Android. However less than 12 hours later, the indicators are green again as though SpamAssassin has been restarted. I don't receive an event message in the app that it really has been restarted though. What can be wrong and how can I really stop SpamAssassin with the indicators turning grey for ever?
