Hi Guys,

I think i found out the culprit to this issue. The main problem of the
GNUTAR to be in hanging state was due to the cancellation of the amdump
process during its execution. This happenned when the amdump (running)
process is being cancelled and were being rerun at a certain point of time.
This thus causes the compression running on the client at that time to wait
indefinitely and hanging in the memory space. This happenned to me and i
have to manually kill it.

By the way guys is there any solution to resume amanda backup if the
internet connection was down for a moment?

Regards,
Anthony
