Hi
I attached the ouput from your command in 10s. Last time i tested, bind did reach to 1Gb but it still hang ( don't respond any query ). Could you help me take a look at this log?

Could you collect some lock statistics using plockstat(1M)? i.e.: # plockstat -e 300 -p `pgrep ^named` The -e 300 causes it to collect statistics for 5 minutes - experiment a little and feed back what is reported. >Mb i will check with other version of bind.
