The use of UpdateSystemActivity(OverallAct) has been deprecated in OSX 10.8.

The recommended approach is now to block it with the following call:

IOPMAssertionCreateWithName(kIOPMAssertionTypePreventUserIdleDisplaySleep,
                            kIOPMAssertionLevelOn, reasonForActivity, &assertionID);

See this Apple Q&A for further details.

i've just solved it and forgot to post it as an answer. Calling UpdateSystemActivity(OverallAct) every 30 seconds works.
