Hello everybody yesterday evening I have update a server with ubuntu 18.04 (just the routine security update, libc, kernel, not cyrus), and after reboot cyrus fails in quite strange way. It works fine for a few minutes, but then the cyrmaster spins up to 100% cpu (1-core), and stops receiving new connections. Processes that exit stay in defunct/zombie state, and eventually all of them end up like that. At first I suspected some SSL problems, so eptied the tls_sessions.db, even set tls_session_timeout: 0, tried to disable mailnotifier (I had it at log), enabled debug, but still can't find the problem. Anybody has/had the same problem and perhaps a solution?
