Hi Fabian, thanks for your response. I tried to install the lates branch, but get a compile error. The latest nightly build works fine, but does not yet contain the changes, so I will probably wait until tomorrow evening. In meantime, I changed the script as follows: =============== begin code // create database (I will replace the ugly sleeps as soon as your fixes are available to me)
monetdb create SchemaDBLP1000 sleep 2 monetdb start SchemaDBLP1000 sleep 2
// load document
mclient -lsql -dSchemaDBLP1000 < document.sql
// stop the database again
monetdb stop SchemaDBLP1000 sleep 2 monetdb destroy -f SchemaDBLP1000 sleep 2 =============== end code
The merovingian process is now started initially, from outside the script. Starting and stopping seems to work fine. First of all, do you agree that this is the intended way (except for the sleeps, which may fail)? However, also in the scenario above exactly every second run fails. The log for four consecutive runs is provided at the end of the mail.
I don't understand yet why you need the kill -KILL on merovingian (it whould kill all mservers in a much nicer way for you than with -KILL when you just normally kill merovingian), but I from what I understand merovingian is just not stopping the databases?
Well, I also tried standard "killall"s, but without any effect.
If so, could you please send me the merovingian.log file?
Here it is, for four consecutive runs of the script above. In run 2 and 4 (which fail), there is a "MSG merovingian[5790]: database 'SchemaDBLP1000' (5832) was killed by signal 11", which seems to reflect the problem. Unfortunately, I do not know what this message means? Thanks again, Michael =============== begin log ////////////////// INITIAL STARTUP TME 2008-02-20 03:12:30 MSG merovingian[5790]: Merovingian 0.6 starting ...
