There is a program called "sage-cleaner" that repeatedly sends kill -9's to any processes that are left running. Processes register themselves in $HOME/.sage/... by creating certain pid files, and if the Sage that started them is no longer running, then the "sage-cleaner" daemon will repeatedly kill them until they die. If sage-cleaner isn't running and you type "sage" at the command line, it is automatically started. It exists a minute or so after all other sage-related processes exit. So, is sage-cleaner running for you when you witness you hung lisp/maxima processes problem? Are there any other sage processes running? If you run Sage again, do the lisp/maxima processes then die? Have a look at local/bin/sage-cleaner, by the way. -- William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
