Hi all, I am using MonetDB Dec 2011 version. Seeing that I could not connect to 'mydatabase' from mclient, I tailed the log: 2012-02-29 11:39:32 MSG mydatabase[7045]: # Serving database 'mydatabase', using 2 threads 2012-02-29 11:39:32 MSG mydatabase[7045]: # Compiled for x86_64-pc-linux-gnu/64bit with 64bit OIDs dynamically linked 2012-02-29 11:39:32 MSG mydatabase[7045]: # Found 999.238 MiB available main-memory. 2012-02-29 11:39:32 MSG mydatabase[7045]: # Copyright (c) 1993-July 2008 CWI. 2012-02-29 11:39:32 MSG mydatabase[7045]: # Copyright (c) August 2008-2012 MonetDB B.V., all rights reserved 2012-02-29 11:39:32 MSG mydatabase[7045]: # Visit http://www.monetdb.org/ for further information 2012-02-29 11:39:32 MSG mydatabase[7045]: # Listening for UNIX domain connection requests on mapi:monetdb:///var/monetdb5/dbfarm/mydatabase/.mapi.sock 2012-02-29 11:39:32 MSG mydatabase[7045]: # MonetDB/SQL module loaded 2012-02-29 11:39:32 MSG merovingian[6978]: database 'mydatabase' (7045) was killed by signal SIGSEGV 2012-02-29 11:39:32 ERR merovingian[6978]: client error: database 'mydatabase' has crashed after starting, manual intervention needed, check monetdbd's logfile for details Any ideas?
