User-Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:53.0) Gecko/20100101 Firefox/53.0
Build Identifier:

If you configure from source using the --program_suffix or --program_prefix flags, monetdbd cannot start any database, because it is forking with the monetdbd executable instead of the mserver5 executable.

Reproducible: Always

Steps to Reproduce:

1. configure --program_prefix=testprefix_
2. make install
3. testprefix_monetdbd create /path/to/dbfarm
4. testprefix_monetdbd start /path/to/dbfarm
5. testprefix_monetdb create testdb
6. testprefix_monetdb start testdb

Actual Results:

starting database 'testdb'... FAILED
start: starting 'testdb' failed: database 'testdb' appears to shut itself down after starting, check monetdbd's logfile (merovingian.log) for possible hints

$ less /path/to/dbfarm/merovignian.log

Expected Results:

The database should start.
