If I start a mserver5 with a corrupted (old) dbfarm I get: # MonetDB server v5.7.0, based on kernel v1.25.0 # Serving database 'rdf_current', using 4 threads # Compiled for x86_64-unknown-linux-gnu/64bit with 64bit OIDs dynamically linked # Copyright (c) 1993-July 2008 CWI. # Copyright (c) August 2008- MonetDB B.V., all rights reserved # Visit http://monetdb.cwi.nl/ for further information #warning: please don't forget to set your vault key! #(see /scratch/romulo/build/MonetDB/current/optimized/MonetDB5//etc/monetdb5.conf) # Listening for connection requests on mapi:monetdb://127.0.0.1:50000/ # MonetDB/SQL module v2.25.0 loaded

Which is correct. However, I am only able to close (I should more say kill it) with kill -9 I could open a bug, but it is not easy to create a test for this problem... Romulo
