Here is output from gdb: ceos@lux-analytics:~$ gdb --args /usr/bin/mserver5 --dbpath=/u01/ceosdata/database/monetdb/drmax/crm/zkdev1 --set merovingian_uri=mapi:monetdb://lux-analytics:50000/zkdev1 --set mapi_open=false --set mapi_port=0 --set mapi_usock=/u01/ceosdata/database/monetdb/drmax/crm/zkdev1/.mapi.sock --set monet_vault_key=/u01/ceosdata/database/monetdb/drmax/crm/zkdev1/.vaultkey --set gdk_nr_threads=4 --set max_clients=64 --set sql_optimizer=default_pipe --dbinit="sql.start();" GNU gdb (Ubuntu/Linaro 7.4-2012.04-0ubuntu2.1) 7.4-2012.04 Copyright (C) 2012 Free Software Foundation, Inc.
