Lynn,
Since you are getting a SIGTERM with limited error messages, you may need to start the crashing process in gdb to get a stack trace. That should help isolate the problem.

Hi all -
Yesterday our monetdb instance seemed to be running slowing, perhaps due to user queries that had been killed but maybe not cleaned up. We decided to stop the dbs, then start/stop monetdbd. I executed the following commands, but was unable to restart the daemon:
sudo monetdbd stop /local/monetdb/dbfarmBL sudo monetdbd start /local/monetdb/dbfarmBL
We had our admin reboot the machine, thinking this would clear up everything. This morning I tried again to start monetdbd. The command comes back with no messages, but I get a connection refused message when trying to access a database:
could not connect to localhost:50000: Connection refused
Get all shows this:
[lcj34@cbsudc01 anp68_ije_Locus9Combined_Result]$ monetdbd get all /local/monetdb/dbfarmBL property value hostname cbsudc01 dbfarm /local/monetdb/dbfarmBL status no monetdbd is serving this dbfarm mserver unknown (monetdbd not running) logfile /local/monetdb/dbfarmBL/merovingian.log pidfile /local/monetdb/dbfarmBL/merovingian.pid sockdir /tmp listenaddr 128.84.3.206 port 50000 exittimeout 60 forward proxy discovery yes discoveryttl 600 control no passphrase <unknown> mapisock /tmp/.s.monetdb.50000 controlsock /tmp/.s.merovingian.50000 [lcj34@cbsudc01 anp68_ije_Locus9Combined_Result]$
The log shows the following message:

Any ideas what to try?
Thanks - Lynn
