FYI, I see the same thing on a RHv9 2.2ghz box with a single TDM04b and no calls being processed. Top indicates 30.6% every 10 seconds. Stopping * has no impact. Stopping zaptel makes that disappear. Starting zaptel only (no asterisk) brings it back to 30.6%. _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
