error in qmail

[kapil sharma]

I am getting the following error in my mail log file:

May 22 18:33:52 localhost qmail: 959000632.425508 alert: unable to append to
bounce message; HELP! sleeping...

What could be the reason?

My server "qmail-queue" process has become zombie. Following is the output of
"ps":
qmailq   11687  0.0  0.0     0    0 pts/4    Z    18:38   0:00 [qmail-queue
<defunctioning>

Is there any way to kill this process and start the server properly. Please
help as I cannot start my online email server!!!


Thank you
