I'm ising freebsd-3.3release box as a gateway. I'm using also some application-level gateway programs Not a long I'd found a kind of DoS at this box. Discovering this situation I'd found, that some gateways (xinetd-started) drops to Zombie state and remains in this state too long (about 40-60 seconds). This disaster appeared sporadically, and machine's load was not sensible high (about 0.07-0.10 by uptime report). There is no sensible network load at this time also. This situation repeats once in about 5 minutes. The question is: what a kind of internal processing causes processes to remain zombie for a long time? Which workarounds may be used to avoid such situations? I cannot stop this service for a long time for upgrade to 3.5-stable or 4.x, therefore I have to try anything else... -- Antuan Avdioukhine (DEKA-RIPN) InternetMedia Holding Ltd.
