Libguestfs - Aug 2009 - how to clear <defunct> qemu-system-x86 processes

Hi all,

I have a long term running program which call libguestfs to check VM 
images. but i found that each time after i call guestfs_close(), the 
qeum-system-x86 process which is forked by libguestfs changes to 
<defunct> process.

as docs of guestfs_close said "This closes the connection handle and 
frees up all resources used.", so this is a bug or is there any other 
way to clear them.

thanks a lot!

It should remove them automatically -- in fact it does for me.

You'll need to give us some more details about your system:

What operating system is this?

What version of libguestfs?

Did you use our binaries or compile it yourself?

Are you using the C API directly?

Do you get the same problem from guestfish or from libguestfs-test-tool?

Yes, I've confirmed this is a real bug.  I've opened a bugzilla entry
for it:
