Yes, I observe that the df command doesn't respond for
quite some time.
 Do you mean that I should run "strace
/usr/sbin/amcheck <config_name>" command?

no, run 'strace -p <pid of selfcheck>'

But don't it if 'df' hang.
You must fix your mount problem:
 - umount not responding partition.
 - reboot

The selfcheck process is hang.
Could you strace it and attach a debugger to it and
get a backtrace.

It's often because of a stale mount point.
Did 'df' succeed?
