I have run tplot on much larger files than that without troubles. Which version are you using? I assume this is the one from hackage which AFAIK is the one I am also using. Could you post a sample input file? Regards, -- Arnaud Bailly FoldLabs Associate http://foldlabs.com

Hi Manish, Please provide the input file, I'll debug this. On Mon, Sep 3, 2012 at 1:06 PM, Manish Trivedi wrote:

Did you ever solve this? I have a similar message ( user error (out of memory) ) arising from a different app (not tplot) that uses the Haskell Chart library (and cairo underneath). On some linux machines, it crashes, on others it works fine. I can find no environment differences between the machines. The app does not use a lot of memory, and the machine is not running out of physical or swap.

Hi, I didn't - because I didn't run into this myself. Manish, maybe you did? :) On Thu, Oct 18, 2012 at 1:55 AM, malcolm.wallace wrote:

For the record, it turned out that the key difference between the linux machines was the fonts packages installed via RPM. The strace utility told me that the crash happened shortly after cairo/pango attempted (and failed) to open some font configuration files. After installing some of the X11 font packages (and some others too), the crash went away. On 18 Oct 2012, at 09:55, malcolm.wallace wrote:

Hi, Wow, that's weird. I wonder what kinds of fonts were missing? I was just using the default cairo font everywhere. On Fri, Nov 30, 2012 at 11:27 PM, Malcolm Wallace wrote:

Hi folks, Just thought it might be helpful to close this issue. Haskell tplot out of memory on centos ep6 was indeed related to the font issue. As Malcolm pointed out, installing x11 fonts resolved the issue. This yum install worked for me "yum install xorg-x11-font*". Thanks, Manish On Fri, Nov 30, 2012 at 11:29 AM, Eugene Kirpichov wrote:
