one of the Zimbra's I manage is a 6.0.1_GA_1816.UBUNTU6 Network Edition that was upgraded from 5.x. We upgraded about 2 weeks ago, and I've had four alerts from my monitoring systems that one of zmstat's processes (zmstat-cpu) stops working.
They all occur around 6:30 AM, which is (if I not mistaken) the time at which some cron/logrotate jobs should run.
Anyone else seing this? Is it a know bug/issue?
