Hi Hugh, There is no error written at the end of the virtuoso.log file.
I'm sorry I'm not sure what you are referring to by "is a core file created whose stack trace can be analysed to determine point of the crash ( shall "ulimit -c" needs to be greater then 0 for core file creation) ?" Which file is this and how can I get virtuoso to create this? isql 1111 dba dba gives me [ISQL]ERROR: Could not SQLConnect I can only get this to work on windows. Would you please let me know how I can get this to work.
