In some cases memory is continually allocated until system slows to a crawl, swapping. Ubuntu 7.10 Scilab package: 4.1.1-1 In comparison, scilab 4.1.2 downloaded as a binary from scilab.org works fine. A previously downloaded 4.1.1 version of Scilab from scilab.org also worked fine (used on an older version of Ubuntu, 6.10 LTS I believe) so it is not fundamentally a scilab problem. Here are some allocation examples between the two (total virtual process size reported). Stacksize() function takes a numeric argument which is the number of 8-byte doubles to increase stack allocation by, so stacksize(4000) should allocate 320 MB to the stack. In these examples, no code is being run or data loaded; just the command line shell is started and the stacksize() command is executed. 4.1.2 produces the expected virtual size; 4.1.1 is roughly double under no activity. With significant code running, my observation is that Ubuntu's 4.1.1 scilab continues to allocate memory well beyond the stacksize() numbers shown below, just doesn't seem to stop allocating (but that's a guess). As a result, Ubutnu's scilab 4.1.1 is unusable. stacksize() 4.1.1 (Ubuntu pkg) 4.1.2 (scilab.org binary release) = 1000 180 MB 96.5 MB 2000 337 MB 174 MB 4000 649 MB 331 MB 1 1.43 GB 800 MB Recommend: fix (presumed) configuration issue with Ubuntu's scilab 4.1.1 package. --- -- Scilab error message -- -- How to reproduce the bug -- Reply at: https://bugs.launchpad.net/ubuntu/+source/scilab/+bug/225070/comments/1 On 2018-03-23T00:16:26+00:00 Sgougeon wrote: stacksize() is removed in Scilab 6.

Re: [Bug 225070] Re: scilab allocates excessive memory
I suspect then that this won't get fixed. It seems to be an Ubuntu problem. The scilab binary works fine, a RedHat version works fine on a similar Fedora release, only Ubuntu doesn't work, all under the same conditions. -Mike --On Monday, September 22, 2008 9:24 PM + Sylvestre Ledru <[EMAIL PROTECTED]> wrote: > This might explain the difference We will see with the version 5 > when it comes up. -- scilab allocates excessive memory https://bugs.launchpad.net/bugs/225070 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

OK. I am using 64-bit CPU and 64-bit Ubuntu 7.10.

Thanks -- you don't think it is an Ubuntu configuration problem? It occurs only with the Ubuntu package version. -Mike --On Monday, September 22, 2008 6:32 PM + Sylvestre Ledru <[EMAIL PROTECTED]> wrote: > Interesting bug ... forwarded upstream: > http://bugzilla.scilab.org/show_bug.cgi?id=3569 -- scilab allocates excessive memory https://bugs.launchpad.net/bugs/225070 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
