Category: SQL/Core Group: MonetDB5 "stable" Status: Open Resolution: None Priority: 5 Private: No Submitted By: Thomas Neumann (tneumann) Assigned to: Niels Nes (nielsnes) Summary: bulkloading a large string table kills mserver Initial Comment: Bulkloading a large string table of the form (id,value) kills mserver. I attached a data generator that generates 21GB of input to illustrate the problem. How to reproduce: - g++ -odatagen -O2 datagen.cpp - ./datagen > test.sql - monetdb create foo - monetdb start foo - mclient -l sql -d foo test.sql results in: ERROR = Connection terminated and the server crashed (on Linux x86_64). Note that there seem to be two problems in one: The primary crash seems to be due to the "primary key" constraints in the table. Dropping it changes the behavior: The bulkload succeeds on a machine with 32GB of main memory, but effectively stops (i.e., swap excessively) on a machine with 2GB of main memory. Adding the primary key constrants after successful bulkloading without it crashes the server, too. ---------------------------------------------------------------------- >Comment By: Niels Nes (nielsnes) Date: 2009-02-12 07:02 Message: The 2GB machine was a 32 or 64 bit system? Loading on a 64 bit machine with 8G seems to work okay (including primary key). ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=482468&aid=2261241&group_id=56967 ------------------------------------------------------------------------------ Create and Deploy Rich Internet Apps outside the browser with Adobe(R)AIR(TM) software.
