Yes, the reductions did not change for at least 15 minutes, so it was 
really stuck.  I did not check it once again though.

Even if I did not report it anywhere, I have seen other processes 
before, ones not related to mnesia or disk_log, got stuck for several 
hours until the node got restarted or process exited.  Unfortunately, I 
have no idea how to reliably reproduce this symptom.

Ciao,
