Dear Sir I have been testing the lastest version of mserver5 under Linux on an embedded arm platform (Marvell PXA270 XScale 600Mhz) and a PC. MonetDB server v5.16.5 kernel v1.34 I have built it for gumstix (arm based platform) and for PC I have built it using the monetdb-install.sh with the following parameters export EXTRA_ECONF="-enable-optimize -disable-debug -enable-strict -with-gcc=arm-angstrom-linux-gnueabi-gcc -host=arm-angstrom-linux-gnueabi -with-openssl=$HOME/gumstix/openssl -without-perl -without-ruby -without-python -without-php -without-java -without-swig without-libxml2 -with-pcre=$HOME/gumstix/pcre . /monetdb-install.sh -nightly=stable -prefix=$HOME/gumstix/monet -build ==$HOME/gumstix/monetBuildGum -enable-sql Unfortunately using 2 instances of my test program (test1.cpp attached) writing to the database at the same time, I see the memory being consumed and not released - it is very noticeable on a gumstix and will use all the memory within a hour. If I stop the writer applications the memory usage remains constant. No further memory is released If I halt the database server and reload the same same database I get a considerable reduction in the memory i.e. mserver5 memory footprint on a gumstix (http://www.gumstix.com/ verdex-pro 11% memory usage at Start running 2 instances of the test application (test1) 35.8% memory running for 3mins then stopping the write (test1) applications 10.3% memory after stopping and restarting database 12.8% memory after reloading database The test programs were run for only a few minutes. I also have valgrind reports of the same programs being run a the pc if helpful Simon Abernethy Software Engineer MiPlaza Philips Research Europe WB6.014 (HTC34 6.14) 5656 AE Eindhoven, The Netherlands Tel +31 40 27 49566 Fax +31 40 27 42081 Email simon.abernethy@philips.commailto:simon.abernethy@philips.com http://www.miplaza.com ________________________________ The information contained in this message may be confidential and legally protected under applicable law.
