MEDIAN(double) not found

Hello, We use MonetDB Jan2014-SP2. When I try MEDIAN function it simply says: MEDIAN: no such operator 'median(double)' [SQL State=22000] Am I missing something? I tried to execute section of 39_analytics.sql containing the MEDIAN function. It says MEDIAN function is already there. Thank you for any tips. Radovan Test Case: I took the sql from bug 2454: select median(id) from sys.tables; result: An error occurred when executing the SQL command: select median(id) from sys.tables MEDIAN: no such operator 'median(int)' [SQL State=22000] Execution time: 0.03s 1 statement failed.

Connection Reset(mserver still alive?)
by Ali Salem 06 Aug '14

Hello, I have recently started using MonetDB for a BI project, and it's doing pretty well. However, I receive a connection reset error each time I run an ETL process (I use Pentaho PDI) to populate my dimensional schema. This error is reported by the MonetDB JDBC driver *Connection reset(mserver still alive?)* This usually happens after a random amount of time, 30 min, 45 min, 1 hour, etc. Any pointers related to this would be very helpful. Specs ------- Ubuntu 12.04 8 GB Ram 500 GB Space Pentaho PDI (community edition) Monetdb5 (installed using apt-get) Thank you.

SIGSEGV during log flush
by Richard Hughes 01 Aug '14

Hello, Can I persuade a developer to help me out with bug 3422 [https://www.monetdb.org/bugzilla/show_bug.cgi?id=3422#c4]? I'm amassing an unhealthy collection of core dumps now (about one a day), and the latest is from Jan2014SP3 which I upgraded to last night. FWIW I'm no longer sure that I am looking at the same SIGSEGV as the one that the original bug reporter was talking about - of course I can create a new Bugzilla entry if it helps. This is our staging platform so I have the ability to run all sorts of custom builds or anything else that will help debug it, I'm just not sure where to start looking; I'd really appreciate some hints. Thanks for your help, Richard.
