[bind10-dev] shutdown / kill errors

Thu Sep 16 23:02:17 UTC 2010

I noticed a few problems when kill -TERM bind10 (boss), CTRL-C, and also 
when using "Boss shutdown". Notice multiple problems in examples below.

$ kill 15049

Also these didn't die on their own:

[bind10] Sending SIGKILL to b10-zonemgr (PID 2454).
