X-Mailer: Mozilla 4.04 [en] (X11; I; FreeBSD 2.2.6-BETA i386) MIME-Version: 1.0 To: freebsd-stable@FreeBSD.ORG Subject: Excessive memory consumption with gnuplot Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG G'day. I've been observing some curious behaviour from gnuplot under 2.2.7-STABLE. Recent responses from gnuplot gnurus seems to indicate that the problem may be OS specific, rather than strictly gnuplot's fault. (Not being a native gnuplot user I wasn't sure what to expect from the package at first.) Here's the story (see kern/8473): Invoking gnuplot 3.5 under FreeBSD 2.2.7-STABLE causes excessive consumption of memory when displaying data. The problem seems to occur above some threshold in input data file size. For example, input data files above about 1 Mb sometimes give rise to 150 - 200 Mb of swap being consumed. One data file tested with a size of 3 Mb caused ~400 Mb of swap to be consumed. This problem is not repeatable under 3.0-RELEASE, or another OS tested (linex 2.0.0) Here's a brief description of the environment: 2.2.7-STABLE 22/09/98 233 MHz Pentium 32 Mb RAM 630 Mb swap gnuplot 3.5 PL340 I have data files available on request for anyone foolhardy enough to test... Any and all help appreciated. -- Brenton Vandepeer, Genesis Software, Pty Ltd. email: bvandepe@gsoft.com.au Adelaide, Australia.
